CAUTION Follow Installation Instructions carefully.
DISCONNECT POWER TO THE HEATER – AIR CONDITIONER BEFORE REMOVING THE OLD THERMOSTAT AND INSTALLING THE NEW THERMOSTAT.

CAUTION

The two Alkaline “AA” batteries must be replaced at least once every 12 months to ensure proper operation. The “Low Battery” icon will appear on the thermostat display when it is time to replace the batteries. If the thermostat is connected to 24v power, the batteries should still be installed, but are not required. When “Low Battery” is displayed the batteries must be replaced immediately. The manufacturer cannot be liable for improper operation of the thermostat if the batteries are not immediately replaced. Annual battery replacement is especially critical in locations subject to freezing temperatures. The thermostat will be unable to turn on the heating system if the batteries are exhausted.

This device complies with Part 15 of the FCC rules.
Operation is subject to the following two conditions:

This device may not cause harmful interference, and
this device must accept any interference received, including interference that may cause undesired operation.

Location of Controls

Display

Heat and Cool Indicators.
- In normal operation, Heat or Cool appears, depending on the Mode Switch position. When heat or cool is energized, the Heat or Cool indicator will flash.
Current room or set temperature.
Desired set temperature indicator.
- When this indicator is on, the large numbers represent the desired room temperature. Pressing the COOLER or WARMER button during normal operation will cause the large numbers to switch from the current room temperature to the desired set temperature.
Indicates battery life is low; it is recommended to replace the batteries at this time.

Normal Operation

Operation

Select Cool or Heat with the Mode Switch. Normally leave the fan switched to Auto.
In Fan Auto, the fan will turn on only with a heat or cool demand. When Fan On is selected, the fan will run continuously.
Adjust the desired set temperature with the COOLER or WARMER buttons.

Fahrenheit or Celsius

Operation

Select Off with the Mode Switch.
Press and hold the COOLER and WARMER buttons at the same time until the temperature is displayed in degrees Celsius.
Repeat this process to display the temperature in degrees Fahrenheit

Preparation

Proper installation of the thermostat will be accomplished by following these step-by-step instructions. If you are unsure about any of these steps, call a qualified technician for assistance

These tools will be required:

Make sure your Heater/Air Conditioner is working properly before beginning the installation of the thermostat.
Carefully unpack the thermostat. Save the screws and instructions.
Turn off the power to the Heating/Air Conditioning system at the main fuse panel. Most residential systems have a separate breaker for disconnecting power to the furnace.

Remove & Replace the Old Thermostat

Remove the cover of the old thermostat. If it does not come off easily check for screws.
Loosen the screws holding the thermostat base or subbase to the wall, and lift away.
Disconnect the wires from the old thermostat.
Tape the ends of the wires as you disconnect them, and mark them with the letter of the terminal for easy reconnection to the new thermostat.
Keep the old thermostat for reference purposes, until your new thermostat is functioning properly.

Battery Replacement

The batteries are easily accessible from the battery slot located on the front of the thermostat (fig. 1). To open the battery slot, press down on the battery cover and pull out
Remove the old batteries and replace with the new AA alkaline batteries
Place the bottom hook of the battery cover into the slot and snap closed

Wire Connections

If the terminal designations on your old thermostat do not match those on the new thermostat, refer to the chart below or the wiring diagrams that follow

Thermal Insulating Sheet

A label is provided on the backplate that prevents drafts originating inside the wall from entering the thermostat.
These drafts, left unchecked, may cause incorrect room temperature readings.
Please do not remove this label from the thermostat. Insert the wires through the slots provided in the label

Test Operation

Turn on the power to the Heating/air conditioning system.
On the thermostat, slide the Mode Switch to HEAT. Press the COOLER or WARMER button until the set temperature is 10 degrees above room temperature.
The HVAC unit should energize in the heating mode (Page 6). Note: You may need to wait up to five minutes for heating to energize due to the compressor lockout feature.
On the thermostat, slide the Mode Switch to COOL. Press the COOLER or WARMER buttons until the set temperature is 10 degrees below room temperature. The
HVAC unit should energize in the cooling mode (Page 6). Note: You may need to wait up to five minutes for cooling to energize due to the compressor lockout feature.
On the thermostat, slide the Mode Switch to OFF. Slide the Fan Switch to Fan On. The fan should turn on and run continuously (Page 6).

Troubleshooting

SYMPTOM: The air conditioning does not attempt to turn on.
CAUSE: The compressor timer lockout may prevent the air conditioner from turning on for a period of time.
REMEDY: Consult the Owner’s Manual in the Installer Setup section to defeat the Cycles Per Hour (page 26).
SYMPTOM: The display is blank.
CAUSE: Lack of proper power.
REMEDY: Make sure the power is on to the furnace and that you have 24vac between R & C.
SYMPTOM: The air conditioning does not attempt to turn on.
CAUSE: The cooling setpoint is set too high.
REMEDY: Lower the cooling setpoint or lower the cooling set-point limit. See Setpoint Limits (page 26).
SYMPTOM: The heating does not attempt to turn on.
CAUSE: The heating setpoint is set too low.
REMEDY: Raise the heating setpoint or raise the heating set-point limit. See Setpoint Limits (page 26).
SYMPTOM: When controlling a residential heat pump, and asking for cooling, the heat comes on.
CAUSE: The thermostat reversing valve jumper is set for B.
REMEDY: Set the reversing valve jumper for O.
SYMPTOM: When calling for cooling, both the heat and cool come on.
CAUSE: The thermostat equipment jumper is configured for HP and the HVAC unit is a Gas/Electric.
REMEDY: Set the equipment jumper for Gas.
SYMPTOM: When the Program button is pressed, the display reads “DISABLED”.
CAUSE: Program mode is set to NON PROGRAM.
REMEDY: Set Program Mode (Setup 1) to 1, 5/2, or 7 Day. See Selecting Your Program Mode
