Introduction • 1EcoLogix, LLC SensorStat® DDC2F Installation & Operation Manual Version 1.1

General Description

SensorStat DDC2-F is designed to replace existing low voltage thermostats and fan speed controls. (Use power control station "PCS" when controlling 110 - 277Vac HVAC units and fan speeds).

SensorStat DDC2-F utilizes advanced process logic to accurately control the room temperature by automatically determining whether heating or cooling is required and by automatically selecting the fan speed necessary to overcome the room heat loss or gain.

NOTE: The DDC 2 and DDC 2F use the same handheld programmer but connecting them to the units is different:

In some cases, the use of door contacts can be eliminated by using the Real Time Clock (RTC) add on module.

RTC may not be used when DDC 2F will be on line with innPULSE

The SensorStat DDC2-F utilizes a combination of door contacts and a state-of-the-art passive infrared (PIR) sensor with Senercomm's unique tamper-resistant "flat" lens, designed specifically for hotel and institutional applications, to sense the presence of people within the room. By knowing the occupancy status of any single room dwelling, with HVAC control within the room, (such as hotel/motel guestrooms) the SensorStat can automatically reduce energy waste by setting back the temperature of the room when the room is unoccupied or unsold. With the addition of remote occupancy sensors, a SensorStat can also be used in multiple room configurations such as suites. This provides an enhanced level of digital HVAC comfort control while automatically reducing energy waste when rooms are unoccupied or unsold.

Basic Operation

The SensorStat DDC2-F appears to the guest as an advanced digital thermostat that is easy to use. Selection of power on/off, fan auto/on, temperature setting and temperature display in Fahrenheit or Celsius are made with easy-to-use pushbuttons and switches. Selections are immediately confirmed by highly visible LED digital display.

Not apparent to the guest are features that allow the HVAC to be automatically switched from heat to cool or vice versa, automatically increase

fan speed to meet increasing heating or cooling demands and to set back the room temperature when the room becomes unoccupied.

Even if the guest has turned the SensorStat "off", once the room is unoccupied, the SensorStat automatically puts itself back on-line so the room environment is never excessively hot or cold.

SensorStat's sophisticated “occupancy-sensitive” logic ensures that the important balance between energy savings and occupant comfort is maintained. SensorStat produces maximum energy savings with minimum guest discomfort.

Standard Components The standard system components for the SensorStat DDC2-F system include the SensorStat DDC2-F with field wiring harness, and door switch(s).

In addition, a power control station, remote motion detectors, and additional door switches may be used. These will be covered now. Other optional components are covered later in this manual.

Door Switches

A closed loop door switch is require: Door closed = switch closed

A door switch is required to send a signal to the SensorStat DDC2-F that a guest has entered or exited the room. We strongly recommend using switches sold by Onity.

IMPORTANT: Although it is a small, inexpensive device, an unreliable or intermittent signal from poor quality or improperly installed door switch will cause strange symptoms, irritate guests and can cost you a lot of money in recurring service calls. Because of the importance of this device, use of non-specified switches is discouraged and may void the SensorStat warranty.

Why do we use specific types of door switches?

Do not use a “steel ball” type switch as it may react to cleaning chemicals and with salt in a beachfront property.

The reason we use specific types of door switches is because SensorStat DDC2-F supplies a small current of only .005 amps to the door switch. Commercial security systems normally supply a much higher current (0.050 - 0.100amp ) to the door switch. In addition, most commercial door switches require a minimum of .035 amps to “wipe” the contacts so they do not oxidize, causing intermittent contact.

Universal Power Control Station

The Universal Power Control Station operates universally across the voltage range from 100 – 277Vac, 50/60Hz

Split – in that the common connection of both the Heat & Cool relays may be separated from the line voltage (100 – 277V) input voltage on Line & Common (L1 & L2). This will allow the heat and cool relay to switch any other voltage supplied to the terminal LHC after the PCS internal jumper has been removed.

Applications: Will allow the PCS to be powered by the 100 -277V that would operate the PCS and the fan motor while allowing for the control of 24V heat or cool valve

6 • Introduction EcoLogix, LLC SensorStat® DDC2F Installation & Operation Manual Version 1.1

The “split” PCS provides an answer to the European concerns that power supplied to heat and cooling valves may be from a different source that the fan motor.

Remote Motion Sensor

In some cases, it is necessary to install a remote Passive Infrared (PIR) sensor. These are most often used in Suite scenarios where one SensorStat is controlling multiple rooms or areas; but can be used in any situation where the SensorStat is unable to sense motion where coverage is needed.

8 • Introduction EcoLogix, LLC SensorStat® DDC2F Installation & Operation Manual Version 1.1

Understanding Temperature Setbacks The fundamental concept of energy management using the SensorStat DDC2-F is that when a guest is in a room, the guest controls the temperature of the room, and when the guest is not in the room, the SensorStat DDC2-F controls the temperature of the room. When the SensorStat is in control of the room, it relies on programmable setbacks to control the temperature in the room.

Figure 3

Unoccupied Summer / Winter Setback

The SensorStat will maintain the setback temperature even if the unit has been powered off by the guest.

When the guest is not physically in the room, the SensorStat DDC2-F goes into unoccupied mode. At this point, it allows the temperature in the room to drift until it reaches the Unoccupied Summer or Winter Setback (see Figure 3). The unoccupied summer setback is the temperature that the SensorStat will allow the temperature to drift to when the temperature is rising in the room and the unoccupied winter setback is the temperature that the SensorStat will allow the room to drift to when the temperature is falling in the room. When the temperature reaches this point, the SensorStat DDC2-F will turn on the HVAC system to cool or heat the room by 2 0F. The temperature will then be maintained in this range until the guest returns to the room, or the SensorStat goes into unsold mode.

Example: Kay is a guest staying at your hotel and sets the thermostat to 680F. At 9am, Kay leaves the hotel, with the thermostat still set to 680F. Because no one is physically in the room, the SensorStat DDC2-F takes over control and allows the temperature to drift to the setback temperature of 760F. During the

Introduction • 9 EcoLogix, LLC SensorStat® DDC2F Installation & Operation Manual Version 1.1

day, while Kay is not in the room, the SensorStat DDC2-F keeps the temperature in the room between 74 and 760F. At 4pm, Kay returns to the room. Control of the room is now passed back to the guest and the SensorStat DDC2-F will drive the temperature down to the set point of 680F.

Note: As soon as Kay opens the door to the room, the SensorStat DDC2-F will turn on the HVAC system with the highest fan speed to quickly drive the temperature to the set point.

Unsold (Deep) Summer / Winter Setback

The SensorStat DDC2-F can be programmed to go into a deep setback mode, called Unsold mode, after 15 hours of unoccupied status. This uses the same premise as the unoccupied setback, but the temperature settings allow for more savings. When this function is enabled, the setback temperatures are 80 0F and 64 0F. This setting allows for even greater energy savings when the room is not sold.

Occupied Limits A third type of temperature setback can be enabled that will impose limits to the temperature range allowed when the room is occupied. For example, you may only want to allow the HVAC system to cool the room to 680F instead of 650F. In this situation, the guest will still be able to set the thermostat to 650F, but the HVAC will shut dow n when the room temperature has reached 680F. For this reason, it is suggested that the SensorStat DDC2-F be programmed to only display the set temperature and not the actual temperature when using occupied limits. Refer to Setting up the SensorStat DDC2-F on page 22 for details.

NOTE: There is a subtle override function that is designed to allow guests (who really want or need the room colder or warmer than the selected limits) to have them without generating a complaint or requiring a trip to the room.

If the occupied limits have been reached and a guest touches the Temperature UP or DOWN button, the limits are removed until the guest leaves and returns to the room. Upon the guest return to the room, the occupied limits are re-activated.

10 • Introduction EcoLogix, LLC SensorStat® DDC2F Installation & Operation Manual Version 1.1

Using the SensorStat DDC2-F

Thermostat Controls The SensorStat DDC2-F is a fully automatic thermostat. The guest simply needs to set the desired temperature of the room and the SensorStat will automatically switch between heating and cooling and change fan speeds as needed to maintain the selected temperature.

Front Panel Controls

There are 4 buttons on the SensorStat DDC2-F:

• Power– Enables or disables thermostat functions for an occupied room. When the room is unoccupied, the thermostat is controlled by setbacks.

• Fan – Fan Modes that the user can access by pushing the Fan button are selected using the handheld programmer. See function chart for handheld programming for more details.

The guest can select programmed fan modes by pressing the fan button. Examples:

Fan Mode selections:

AUTO

Pushing the Fan button will display the following functions:

• Fan Auto function selected with HHP

a. “Fan Auto”

b. “Fan”

Fan Manual selected with HHP (Be sure to select the correct fan speeds available for this HVAC unit).

• Fan

c. Low

d. Medium

e. High

Using the SensorStat DDC2-F • 11 EcoLogix, LLC SensorStat® DDC2F Installation & Operation Manual Version 1.1

Fan Auto - The SensorStat will turn the fan on only when cooling or heating the room and control the speed based on the temperature difference between the setting and the actual room temperature.

Fan Manual – Manual selection of fan speed by guest leaves the fan speed set at selection until changed by the user by pushing the Fan button. To turn fan off, turn DDC 2F power to Off.

• Warmer / Cooler – Use these buttons to set the desired room temperature.

One additional control is the Fahrenheit / Celsius slide switch located on the left side of the unit. Use this switch to choose the way the temperature is displayed - 0F or 0C.

• Select display in F or C

Pushing the button on the left side of the unit will toggle the display of temperature in F and C

Automatic Heat/Cool Switching

The guest need only set the desired temperature. The SensorStat will do the rest.

The SensorStat DDC2-F will automatically switch between heating and cooling as necessary to maintain the desired temperature. To change modes, the temperature must vary by 3 0F in the opposite direction of the current mode.

For Example: The SensorStat DDC2-F is set to 720F, is in cool mode, and the room is occupied. If the temperature rises to 740F, the air conditioning is turned on until the room reaches the desired temperature of 72. At night, the temperature begins to fall. When the temperature in the room reaches 690F, the SensorStat switches to Heat mode and begins to heat the room until the desired temperature of 720F is reached.

In order for the SensorStat to switch back to Cool mode, the room temperature will have to reach 750F.

The guest does not need to do anything for this to happen. The only thing required of the guest is to select the desired room temperature; the SensorStat DDC2-F will do the rest.

Note: If you have a 2 Pipe system with hot water in the pipes in the winter and cold water in the pipes in the summer, you must install a Strap-On Thermostat or Aqua-Stat.

Modes of Operation The SensorStat DDC2-F has four functional modes of operation. The mode that the unit is in is determined by occupancy status and time.

Occupied Mode

When the fan is set to On, it will run in the low fan speed when the temperature equals the

When a guest is in the room, the SensorStat DDC2-F operates as a thermostat, giving control of the HVAC system to the guest. The guest can select the desired temperature using the warmer and cooler buttons, set the fan to automatic operation or to

12 • Using the SensorStat DDC2-F EcoLogix, LLC SensorStat® DDC2F Installation & Operation Manual Version 1.1

always on, and turn the power to the HVAC system on or off. SensorStat setting.

The SensorStat DDC2-F determines occupancy status using a combination of door switches and motion sensors. The room is in occupied control mode in the following scenarios:

• Door Closed + Motion – When the door is closed and the SensorStat DDC2-F senses movement in the room, the system is locked into occupied mode. The unit will remain in occupied mode until the door is opened again.

• Door Open + Motion – When the door is opened and the SensorStat DDC2-F senses movement in the room, the system will be in occupied control mode for a period of 16 minutes. Anytime motion is detected, the SensorStat DDC2-F operates as if the room was occupied for 16 minutes. If no motion is detected in the 16 minute period, the unit changes to unoccupied control mode.

Unoccupied Mode

When the room is unoccupied, the HVAC system is controlled by the SensorStat, not the guest. The SensorStat will now allow the temperature in the room to drift to the unoccupied summer or winter setback. Refer to the Unoccupied Summer / Winter Setback on page 9 for a detailed discussion on setback temperatures. The determination of occupancy status is made using a combination of door switches and motion sensors. The following scenarios will cause the SensorStat DDC2-F to go into unoccupied mode:

• Door Closed + No Motion + 8 minutes – If no motion is detected after the door is closed, the SensorStat DDC2-F will revert to unoccupied mode after 8 minutes.

• Door Open + No Motion + 16 minutes – If the door is open, the SensorStat DDC2-F will revert to unoccupied mode after 16 minutes.

When the SensorStat is in unoccupied mode, the settings of the guest do not matter. Even if the SensorStat is powered off, the unit will turn on the HVAC system when the setback temperature is reached.

Refresh Cycle

If the SensorStat DDC2-F is in cool mode, the refresh cycle is enabled when the room is unoccupied. This means that every 22 minutes, the SensorStat will power on the HVAC unit for a period of 2 minutes, even if the setback temperature has not been reached. This refreshes the room to avoid stale air.

Using the SensorStat DDC2-F • 13 EcoLogix, LLC SensorStat® DDC2F Installation & Operation Manual Version 1.1

Lighting Control

If using the SensorStat DDC2-F to control the lights in guestrooms, be sure to use relays with N/C (normally closed) contacts properly rated for the load they will be controlling. See description and flow chart below to understand the logic functions.

Note: If using the RTC, lighting control is not available.

Set up unit for lighting control by using the handheld programmer:

1. Turn on the lighting function for SP2 output

2. Select the “entry” door with HHP;

• If the Interior door is selected as “entry” door, it is required that both an interior door and an exterior door or window be connected to the DDC 2F and that these inputs be enabled.

• If the Exterior door is selected as “entry” door, you cannot connect the interior door to the DDC 2F. Interior door must be disabled and not used.

Interior Door selected as the Entry Door

• When the interior door is open, lights will remain ON

• When the interior door is closed and NO Motion is detected, lights will be ON for a fixed 32 minute then turn OFF. NOTE: The fixed 32 minute lighting timer is not related to the selectable, open/close door timers.

• When the Interior door is closed and 32 minute timer has timed out without the unit seeing motion, the lights will turn OFF. If motion is detected any time after the 32 minute timer has expired and the lights have been turned OFF, the lights will immediately turn on.

• If the exterior (patio) door or window is opened or closed (while the interior door remains closed, the lights will remain ON regardless of the position of the exterior door. Lights will only turn off after the interior door has been opened and closed, 32 minutes have timed out and no motion was detected.

• When the interior door is opened and left open, the lights will remain ON

• When interior door is opened and closed and Motion is detected, lights will stay ON.

• If the interior door is closed and NO Motion is detected, lights will be ON for a fixed 32 minute then turn OFF.

NOTE: None of the lighting control discussed in this section is connected to the HVAC control functions. Lighting is independent.

Unsold Mode

When the room has been unoccupied for a period of 15 hours, the SensorStat DDC2-F will enter the Unsold, or Deep Setback, mode if enabled. This allows for even greater energy savings in rooms that have not been sold. In this mode, the SensorStat operates just like in Unoccupied mode, but with deeper setback temperatures (Unsold Summer / Winter Setback temperatures).

A housekeeper or other staff member entering the room will not reset the 15 hour timer as long as the door is left open while in the room. The SensorStat will control temperature based on the set temperature for a period of 16 minutes if motion is sensed, but will not reset the unsold timer unless the door is closed and motion is detected.

Soft Bypass®

To cancel Soft Bypass mode, press the Power and Fan buttons at the same time.

At times it may be necessary to bypass the energy management features of the SensorStat. Typically this is done when a guest complains that the room temperature is not kept at the set point when not in the room. To bypass the unit, press the Power and Cooler buttons at the same time. The display will show ‘BP’ which means bypass. The SensorStat will act as a thermostat only for 48 hours. To cancel Soft Bypass mode, press the Power and Fan buttons at the same time. The display will show ‘CA’. The SensorStat will automatically cancel soft bypass mode after 48 hours.

Setting Up SensorStat DDC2-F

Installation Because the SensorStat DDC2-F may be used to control a variety of HVAC systems, the installation will vary depending on the type of system you will be controlling with the SensorStat. This section will provide basic guidelines for installing and wiring the SensorStat.

Mounting Precautions

When selecting a place to mount the SensorStat, avoid the following locations:

• Directly facing any object or device that changes temperature rapidly (e.g. heat strip, fire place).

• In direct sunlight.

• Directly above a heat producing device such as a lamp or TV.

• In the direct air flow of the HVAC vent.

• Where the SensorStat’s motion sensor is obstructed by furniture, walls, or the opening of a door which hides the SensorStat.

Mounting the SensorStat

Selecting the Mounting Location

The PIR (Passive Infrared) detection pattern of the SensorStat works best when the SensorStat is mounted 5 – 6 feet above the floor. Be sure to choose a location that gives the SensorStat the best unobstructed view of the room. A typical placement is shown in Figure 4

Setting Up SensorStat DDC2-F • 17 EcoLogix, LLC SensorStat® DDC2F Installation & Operation Manual Version 1.1

Figure 4

Mounting Instructions

The mounting plate of the SensorStat will mount to a standard 2” x 4” J-box. Once the mounting bracket is installed, the SensorStat snaps onto the bracket.

Field Wiring Connections The SensorStat DDC2-F comes with a Field Wiring Harness for easy connection of the wires to the SensorStat. The wiring harness is connected on the back of the SensorStat DDC2-F by plugging it into J1.

Field Wiring Connection J1

Figure 5

Connect the wires of the field wiring harness to control the various functions of the HVAC unit. The exact wiring will vary depending on the type of unit you are connecting to. For example, you may need to connect to a Power Control Station or you may connect directly to a low voltage control panel. Also, you may not use all the available connections, depending on the HVAC Unit.

Programming the SensorStat DDC2-F The DDC 2F requires the use of the Handheld Programmer

The SensorStat DDC2-F is designed to control many different types of HVAC systems. Because of this, it is very important that the unit is properly programmed in order to work correctly.

Before programming the SensorStat, carefully review the features and functions of your HVAC system so that you can program the SensorStat correctly.

For example, if you HVAC system only has 2 fan speeds, you will need to set up the SensorStat accordingly or the system will not function properly.

Preparing to Program SensorStat

The following information about your HVAC system must be known in order to properly program your SensorStat:

• Available Fan Speeds (1, 2, or 3) – If your system has 2 fan speeds, low and high, choose maximum fan speed 2 when programming the unit.

• Type of HVAC System (Standard or Heat Pump)

• If Heat Pump – Type B or O

• Using Aquastat (Strap-on thermostat) – 2-pipe systems usually use these.

In addition to the information about your HVAC system, you will need to decide how you want SensorStat to function. To make these decisions, you must first understand what choices you have and what they mean.

Following are the options available and a discussion on what each option is.

• Unoccupied Setback Temperature range As discussed in the Introduction to this manual, setbacks are the fundamental concept of energy management using the SensorStat. The settings you choose will determine how much energy you will save when the guest is not in the room. The lower the unoccupied winter setback and the higher the unoccupied summer setback, the more energy will be saved. When deciding what unoccupied setback range to choose, you need to balance energy savings with guest comfort. The range you choose should be based on your individual goals.

• Occupied Limits The temperature setting range of the SensorStat is 650F to 900F. However, if you prefer to limit this range, you can impose Occupied Limits on the guest. When this is done, the guest can

Setting Up SensorStat DDC2-F • 21 EcoLogix, LLC SensorStat® DDC2F Installation & Operation Manual Version 1.1

still set the temperature on the SensorStat to anywhere in the range of 65 - 900F; however, the SensorStat will turn the air handler off when the occupied limit is reached. For example, Mark is a guest at your property. He enters the room and immediately sets the temperature to 650F. Because you have imposed an occupied limit of 680F, the air handler will shut off at 680F.

• Enable / Disable Auto Unsold Setback When a room is unsold, the SensorStat DDC2-F has the ability to enter a deep setback mode. If enabled, the SensorStat will enter unsold mode after 15 hours of being unoccupied. When this happens, the temperature is allowed to increase or decrease beyond the unoccupied setback level to the unsold setback temperature, which is 80 for summer and 64 for winter.

• Display Set or Room Temperature The SensorStat has the ability to display the actual room temperature or display the temperature that has been set by the guest, and you must decide which you want displayed before programming the unit. If occupied limits are enabled, Onity suggests that you choose to display the set temp only. If a guest sets the temperature to 650F and the air handler turns off at 680F, the guest may believe that there is a problem with the air handler.

• Aquastat Function

The Aquastat function, when enabled, will turn on both the heat and cooling outputs on together for 30 seconds then only the output called for based on the room temperature and the set temperature of the stats. This is to allow water to flow through the pipe the Aquastst is connected to forcing it into the correct position for the temperature of the water running in the pipe. This prevents incorrect Aquastst contact positioning when the temperature of the pipe at the Aquastst has cooled off or warmed up to a temperature within the Aquastst dead-band.

You are now ready to program your SensorStat DDC2-F. The following section explains how to do this.

Setting up the SensorStat DDC2-F

The SensorStat DDC2-F is set up for basic installation by using jumpers and switches located on the rear of the unit. There are a total of 16 DIP switches on the rear of the unit (DIPSW1 & DIPSW2) that provide various initial set-up features. The settings/features are shown in the following table.

30 • Setting Up SensorStat DDC2-F EcoLogix, LLC SensorStat® DDC2F Installation & Operation Manual Version 1.1

Functional Testing w/Handheld Programmer (HHP)

Full functional testing will require the Handheld Programmer (HHP) to be connected to the DDC 2F and it set to “View Stat”. Be sure that the baud rate on the DDC 2F matches that of the Handheld Programmer.

Using the HHP in the “view stat” mode, you will be able to monitor the following functions:

• Temperature

• Humidity

• Occupied

• Unoccupied

• Interior Door Open/Close

• Exterior Door Open/Close

• Output Status (W, Y, RV, S1, S2)

• Fan Speed (G1, G2, G3)

• Input Status (A & B)

The following procedures should be followed to test the functionality of the SensorStat DDC2-F.

First, ensure that the temperature in the room is between the unoccupied winter and unoccupied summer setback temperatures. For example, if you have programmed the unit with an unoccupied winter setback of 680F and an unoccupied summer setback of 760F, the temperature in the room must be between 690F and 750F.

To speed up the testing, set the unit into Fast Clock mode. This is done by pressing the Power and Warmer buttons simultaneously (‘FC’ will be displayed). The SensorStat will operate in fast clock mode for 18 minutes and then automatically revert to normal mode.

To manually cancel fast clock mode, press Power and Fan simultaneously.

Occupied Room Test

Before starting the tests, make sure the LED’s are enabled by turning DIPSW2-6 ON and set the SensorStat into fast clock mode. Note: Your HVAC unit may have a dwell time feature to guard against short cycling of the compressor. If so, the unit will not turn on for about 3 minutes after the compressor has shut off. This fact must be considered when performing these tests.

Remember to set the SensorStat into fast clock mode when performing diagnostic testing.

• Close the door(s) – The Door LED should be off.

• Set the temperature 5 degrees below the actual room temperature. You should see the COOL symbol illuminate on the DDC 2F display. Check the air handler in the room to ensure that it is in fact cooling. Allow the unit to run for about 20

Setting Up SensorStat DDC2-F • 31 EcoLogix, LLC SensorStat® DDC2F Installation & Operation Manual Version 1.1

seconds, insuring that the COOL symbol on the DDC 2F does not go off during this time. (The 20 second period is the equivalent of 20 minutes because the unit is in fast clock mode. Making sure the unit runs for 20 seconds ensures that the unit is not going into unoccupied mode.

• Now set the temperature 5 degrees above the actual room temperature. You should see the HEAT symbol illuminate on the DDC 2F display indicating that the unit is heating. Check the air handler to ensure that it is in fact heating. Allow the unit to run for about 20 seconds, insuring that the LED does not go off during this time.

• Walk around the room. Make sure that the Red Motion LED on lights up as you move, indicating that motion is detected.

Unoccupied Room Test

Before starting the tests, make sure the LED’s are enabled by turning DIPSW2-6 ON and set the SensorStat into fast clock mode. and set the SensorStat into fast clock mode. Note: Your HVAC unit may have a dwell time feature to guard against short cycling of the compressor. If so, the unit will not turn on for about 3 minutes after the compressor has shut off. This fact must be considered when performing these tests.

Remember to set the SensorStat into fast clock mode when performing diagnostic testing.

• Ensure that the room temperature is between the winter and summer setback temperatures.

• Disable the motion sensor by setting DIPSW2-5 to the on position. If there is a remote motion sensor installed that will pick up motion in the area, it must be either disconnected or covered so it will not pick up motion.

• Set the unit into fast clock mode.

• Set the temperature on the unit so it is 5 degrees or more different than room temperature. Ensure that the unit is either heating or cooling.

• Open the door, note the door opened on HHP.

• Close the door, note the door closed on HHP.

• After 8 seconds, the unit should turn off, indicating that the unit is in unoccupied mode.

• Turn DIPSW2-5 to the off position. When motion is again detected the HVAC unit turn back on

When the tests are completed, enable the motion sensor by turning DIPSW2-5 to the off position. Remove the yellow jumper from the pins next to the LED’s, and clear the fast clock mode by pressing the Power and Fan button simultaneously (The SensorStat will automatically cancel fast clock mode after 18 minutes).

Don’t forget to enable the motion sensor when the test is finished.

Using the Rear Diagnostic Board

Figure 9

If the air handler is not functioning as it should, and the SensorStat DDC2-F appears to be functioning properly based on the tests, the Rear Diagnostic board should be used to test the outputs of the SensorStat.

To connect the rear diagnostic board:

• Remove the SensorStat from its mounting bracket.

• Disconnect the field wiring harness.

• Connect the rear diagnostic board to connector J4 (the connector that the field wiring harness connects to). The LED’s of the diagnostic board should be to the left of the SensorStat.

• Connect the field wiring harness to the rear diagnostic board.

• Set the Remote Switch On, and the Door switches to Normal.

Run the occupied and unoccupied room tests, insuring that the outputs respond as they should. If the outputs respond as they should, but the air handler does not, the problem is not the SensorStat, but is either in the wiring or the air handler itself.

Example: If the Fan speed 1 LED is on, but the fan does not run, the problem is most likely a broken wire or bad connection between the SensorStat and the fan relay, the fan is burned out, or there is no power to the fan.

Appendix A

SensorStat DDC 2F Control Description This functional description presumes the SensorStat DDC2-F starts out in Cool Mode and the room is occupied.

Begin with temperature set on the SensorStat the same as current room temperature.

• When the temperature in the room rises 1 degree above the current setting on the SensorStat, the cooling output (output Y) and the fan speed 1 (output G1) turn on beginning the cooing process. These outputs will remain on until:

• The temperature in the room increases to 2 degrees higher than the current SensorStat setting. At this time fan speed 2 (output G2) turns on and output G1 turns off

• The temperature in the room increases to 3 degrees higher than the current SensorStat setting. At this time fan speed 3 (output G3) turns on and output G2 turns off

• The room temperature is 1 degree below the selected temperature on the SensorStat at which time the cooling (Y) and fan 1 (G1) will turn off.

Automatic Heat/Cool Mode Switching

When the room temperature drops to 3 degrees below the current setting on the SensorStat, the SensorStat automatically switches from the cooling mode to the heating mode turning output (W) and fan speed 3output (G3) on.

The Heating control operates the same as cooling outlined above as room temperature drops except the heat output (W) is used.

The fan speed control functions in the heating mode work the same as in the cooling mode as described above.

When in the heating mode and the temperature rises 3 degrees above the current SensorStat setting, the SensorStat switches back to the cooling mode.
