INSTALLATION
When Installing this Product…
Selecting Location
Install the comfort control about 5 ft. (1.5m) above the floor in an area with good air circulation at average temperature. See Fig. 1.
- Read these instructions carefully. Failure to follow the instructions can damage the product or cause a hazardous condition.
- The installer must be a trained, experienced service technician.
- After completing installation, use these instructions to check out the product operation.
Do not install the comfort control where it can be affected by:
- Drafts or dead spots behind doors and in corners.
- Hot or cold air from ducts.
- Radiant heat from sun or appliances.
- Concealed pipes and chimneys.
- Unheated (uncooled) areas such as an outside wall behind the comfort control.
Installing Wallplate
The comfort control can be mounted horizontally on the wall or on a 4 in. x 2 in. (101.6 mm x 50.8 mm) wiring box.
- Position and level the wallplate (for appearance only).
- Use a pencil to mark the mounting holes.
- Remove the wallplate from the wall and, if drywall, drill two 3/16-in. holes in the wall, as marked. For firmer material such as plaster, drill two 7/32-in. holes. Gently tap anchors (provided) into the drilled holes until flush with the wall.
- Position the wallplate over the holes, pulling wires through the wiring opening. See Fig. 2.
- Insert mounting screws into the holes and tighten.
WIRING (FIG. 5-15)
All wiring must comply with local electrical codes and ordinances.
- Select a set of terminal identifications (Table 2) that corresponds with the system type (heat/cool or heat pump in Fig. 3).
- Loosen the screws for the appropriate system type selected; see Table 2. Insert wires in the terminal block under the loosened screw. See Fig. 4.
- Securely tighten each screw.
- Push excess wire back into the hole.
- Plug the hole with nonflammable insulation to prevent drafts from affecting the comfort control.

Powering the Comfort Control
The Comfort Control can be powered with 24 Vac. 24 Vac Common Power (Recommended) Wire the common side of the transformer to the B screw of the comfort control wallplate. When installing in a single transformer system, keep the jumper wire between the R and Rc screws. When installing in a two-transformer system, use the common from the cooling transformer to connect to the B screw and remove the jumper wire between the R and Rc screws.
Battery Power (Optional)
Three AAA alkaline batteries can be used to power the comfort control for armchair programming only. To prevent the comfort control and heating/cooling system from shutting down due to lack of battery power, it is not recommended that the comfort control be solely powered with the three AAA batteries during normal system operation. When using batteries, make sure positive and negative terminals are oriented correctly, as marked on the device. See Fig. 16.
Mounting the Comfort Control
- Align the terminal screw blocks with the pins on the back of the comfort control.
- Push the comfort control straight onto the wall plate. See Fig. 17.
Adjusting Real-Time Clock
Setting Calendar and Time
Locate and remove the tab labeled Remove in the lower left corner on the comfort control back. The tab must be removed to activate the real-time clock. See Fig. 18.
This comfort control is designed to automatically keep the current time and day in memory for up to ten years under normal use once the calendar is set. When the comfort control is first powered, the display is ready for the calendar date to be entered. See Fig. 19.
IMPORTANT: The tab on the back of the comfort control in the lower left corner must be removed for this feature to be active.
Using the Comfort Control
The comfort control has a touchscreen interface. Words or symbols appear, highlighting the keys, as necessary, to complete tasks. Always press the keys with your fingertips. Sharp instruments like a pen or pencil point can damage the comfort control.
- Use the arrow keys to set the Year, Month, and Day, as shown in Fig. 19.
- Press the Done key.
- Use the arrow keys to set the current time. See Fig. 19.
- Press the Done key.
OPERATION
System and Fan Settings
The System’s default setting is Heat and the Fan default setting is Auto.
SYSTEM SETTINGS
- Heat: controls heating system.
- Off: The heating and cooling are off.
- Cool: controls cooling system.
- Auto: automatically changes between heating and cooling systems, depending on indoor temperature. (See Installer Setup section.)

FAN SETTINGS
The Fan setting can be programmed into the comfort control schedule for each period (Wake, Leave, Return, Sleep). See the Owners’ Guide for additional information.
LED Indication (Requires 24 Vac Common Connection)
An LED indicator is located in the upper right corner of the comfort control. It is only visible when lighted:
- It indicates when the comfort control is in the Emergency Heat mode. When in Em. Ht. mode, the
F terminal is continuously energized and the LED is on. - When the F terminal is wired to an equipment monitor, the LED signals when a check or fail signal is sent to the comfort control from the system. See Fig. 20. (This can occur only when the comfort control is not in Em. Ht. mode.)

ADVANCED FEATURES
Outdoor or Indoor Temperature Sensor
For accuracy, the initial reading of the indoor and outdoor temperature sensors require five minutes to stabilize. See the Sensor instructions for installation information.
Special Heat Pump Features
Heat Pump with Fossil Fuel Auxiliary Heat (Dual Fuel) and Outdoor Temperature Sensor In this operation there is no external fossil fuel kit (dual fuel kit) installed; the comfort control controls this function.
- Choose correct heat pump application in Installer Setup Number 0170.
- Choose Fossil Fuel Option as the backup heat source in Installer Setup Number 0200.
- Choose No External Fossil Fuel Kit Option as controlling backup heat in installer Setup Number 0210.
- Outdoor Temperature Sensor for Control Option is automatically chosen in Installer Setup Number 0340.
- Choose appropriate Balance Point Temperature in Installer Setup Number 0350.
OPERATION IN HEAT MODE ABOVE BALANCE POINT (OUTDOOR TEMPERATURE)
When the outdoor temperature is above the selected Balance Point Temperature (ISU 0350), only the
compressor operates and the fan (G terminal) energizes when the comfort control calls for heat.
OPERATION IN HEAT MODE BELOW BALANCE POINT (OUTDOOR TEMPERATURE)
When the outdoor temperature is below the selected Balance Point Temperature (ISU 0350), only the Fossil Fuel (auxiliary heat) operates and the fan (G terminal) does not energize when the comfort control calls for heat.
OPERATION IN EMERGENCY HEAT MODE
The balance point (outside) temperature is not used in the Emergency heat mode. When the comfort control is moved to the Emergency Heat position, the compressor is locked out. The first stage of heat is whatever is connected to the X2 terminal. The second stage of heat is what is connected to the W1 terminal. Often there is only one source of non-compressor heat and the X2 terminal is jumpered to the W1 terminal. Heat Pump with Electric Auxiliary (Backup) Heat and Outdoor Temperature Sensor
- Choose correct heat pump application in Installer Setup Number 0170.
- Choose Electric as Auxiliary (Backup) Heat Source in Installer Setup Number 0200.
- Choose Outdoor Temperature Sensor for Control Option in Installer Setup Number 0340.
- Choose Compressor Lockout Temperature in Installer Setup Number 0350.
- Choose Auxiliary Lockout Temperature in Installer Setup Number 0360.
NOTE: There is a 5°F deadband between the Compressor and Auxiliary Heat Lockout Temperatures
OPERATION IN HEAT MODE
When the outdoor temperature is below the Compressor Lockout Temperature, only the Auxiliary Heat operates. When the outdoor temperature is above the Auxiliary Lockout Temperature, only the Compressor operates. See Fig. 21.
When the outdoor temperature is between the two temperatures, both the Compressor and Auxiliary Heat operate.
OPERATION IN THE EMERGENCY HEAT MODE
Once the comfort control is placed into the Emergency Heat mode, the compressor and auxiliary lockout features are turned off. In the Emergency heat mode, the compressor is locked out. The first stage of heat is whatever is connected to the X2 terminal. The second stage of heat is connected to the W1 terminal. Usually the emergency and auxiliary heat sources are electric strip heat in these cases.
Dehumidification Droop Control
The dehumidification control attempts to control to the user’s humidity setpoint by turning on the air conditioner. In extremely high humidity conditions, the comfort control keeps the air conditioner running for up to 3°F below the temperature setpoint. It does this while trying to achieve the desired humidity setpoint and balancing that with the temperature setpoint.
