Battery Replacement
To replace batteries, set system to OFF, remove thermostat cover from wall and install the batteries in the bottom of the thermostat. For best results, use a premium brand “AAA” alkaline battery. If the home is going to be unoccupied for an extended period (over 3 months) and “ ” is displayed the batteries should be replaced before leaving
CAUTION
- Replace batteries when “Change ” is displayed.
- “Change ” indicates batteries have limited remaining life.
- System will not operate with dead batteries
CAUTION
- To prevent compressor and/or property damage, if the outdoor temperature is below 55°F,
- DO NOT operate the cooling system.
- Do not allow the compressor to run unless the compressor oil heaters have been operational for 6 hours and the system has not been operational for at least 5 minutes.

THERMOSTAT OVERVIEW
Before you begin using your thermostat, you should be familiar with its features, display and the location/operation of the thermostat buttons and switches.
THERMOSTAT OPERATION
THE THERMOSTAT BUTTONS AND SWITCHES
-
(Up arrow) Raises temperature setting.
-
(Down arrow) Lowers temperature setting.
-
FAN switch (ON, AUTO).
-
SYSTEM switch (COOL, OFF, HEAT).
THE DISPLAY -
is displayed when the SYSTEM switch
- is in the HEAT position.
- is displayed (non-flashing) when the
-
SYSTEM switch is in the COOL position.
-
is displayed (flashing) when the compressor is in lockout mode (5 minute minimum off time).
-
Displays current temperature.
-
is displayed when the 2 “AAA” batteries are low and should be replaced. Nothing else will be displayed.
-
Displays currently set temperature (this is blank when SYSTEM switch is in the OFF position).
Whenever appears in the display, new premium brand AAA alkaline batteries should be installed. If the house will be unoccupied for an extended period and is displayed, install new batteries before leaving
OPERATING FEATURES
Now that you are familiar with the thermostat buttons and display, read the following information to learn about the many features of the thermostat.
- SIMULTANEOUS HEATING/COOLING SETPOINT STORAGE — You can enter both your heating and cooling setpoints at the same time. There is no need to re-enter the thermostat at the beginning of each season.
- TEMPERATURE SETTING — Press or until the display shows the temperature you want. The thermostat will keep the room temperature at the selected temperature.
- °F/°C CONVERTIBILITY — The factory default setting is Fahrenheit. Clipping W904 jumper on the circuit board will alter this feature to Celsius temperature setting. See the diagram on page 11.
LOW BATTERY INDICATOR — If the 2 “AAA” alkaline batteries are low and
should be replaced, the display will be blank except for
When the batteries are low, pressing any button will cause the display to
operate for ten seconds. After ten seconds, the display will be blank except
for . After has been displayed for 4 weeks, the thermostat will raise the
temperature 10° above your setpoint in COOL mode and drop the temperature 10°
below your setpoint in HEAT mode.
TEMPERATURE DISPLAY ADJUSTMENT — Your new thermostat has been accurately set in our factory. However, if you wish, you may adjust your new thermostat temperature display to match your old thermostat. This can be accomplished (within a ±3° range) as follows:
- Press or at the same time for two seconds with the SYSTEM switch in OFF position.
- Press or to adjust the displayed temperature to your desired setting
- Move SYSTEM switch from OFF to exit the feature
DISPLAY BACKLIGHT — The display backlight improves display contrast in low lighting conditions. Selecting backlight ON will turn the light on for a short period of time after any button is pressed. Selecting backlight OFF (default) will keep the light off. Turn the display backlight feature ON as follows:
- Press and at the same time for two seconds with the SYSTEM switch in HEAT position. The display will alternately show “-L” AND “FF” (off).
- Press or to change “FF” to “ON.”
- Move SYSTEM switch to OFF to exit the feature.
TROUBLESHOOTING
Reset Operation
If a voltage spike or static discharge blanks out the display or causes erratic thermostat operation you can reset the thermostat by pressing and at the same tie while moving the SYSTEM switch from OFF to HEAT. This also resets the factory defaults.
If the thermostat has power, has been reset and still does not function correctly contact your heating/cooling service person or place of purchase.
Batteries
For best results, replace batteries once a year with new premium brand alkaline battery
SYMPTOM | POSSIBLE CAUSE | CORRECTIVE ACTION |
---|
No Heat/ No Cool/ No Fan
(common problem)
| 1.) Blown fuse or tripped circuit breaker 2.) Furnace power switch to OFF
3.) Furnace blower compartment door panel loose or not properly installed
|
1.) Replace fuse or reset breaker 2.) Turn switch to ON
3.) Replace door panel in proper position to engage safety interlock or door switch
No Cool
|
1.) System Switch not set to Cool
2.) Loose connection to thermostat or system 3.) Cooling System requires service or thermostat requires replacement
| 1.) Set System Switch to Cool and lower setpoint below room temperature. 2.) Verify thermostat and system wires are securely attached.
3.) Same procedures as diagnostic for “No Heat” condition except set the thermostat to Cool and lower the setpoint below the room temperature. There may be up to a five minute delay before the thermostat clicks in Cooling.
No Heat
|
1.) Pilot light not lit
2.) System Switch not set to Heat
3.) Loose connection to thermostat or system 4.) Furnace Lock-Out Condition. Heat may also be intermittent.
5.) Heating System requires service or thermostat requires replacement
| 1.) Re-light pilot.
2.) Set System Switch to Heat and raise the setpoint above room temperature. 3:) Verify thermostat and system wires are securely attached.
4.) Many surfaces have safety devices that shutdown when a lock-out condition occurs. If the heat works intermittently contact the furnace manufacturer or local service person for assistance.
5:) Diagnostic: Set SYSTEM Switch to HEAT and raise the setpoint above room temperature. Within a few seconds the thermostat should make a soft click sound. This sound usually indicates the thermostat is operating properly. If the thermostat does not click, try the reset operation listed below. If the thermostat does not click after being reset contact your heating and cooling service person or place of purchase for a replacement. If the thermostat clicks, contact the furnace manufacturer or a service person to verify the heating is operating correctly.
Heat, Cool or Fan Runs Constantly
| 1.) Possible short in wiring.
2.) Possible short in thermostat.
3.) Possible short in heat/cool/fan system. 4.) FAN Switch set to Fan ON.
| Check each wire connection to verify they are not shorted or touching together. No bare wire should stick out from under terminal screws. Try resetting the thermostat as described above.
If the condition persists the manufacturer of your system or service person can instruct you on how to test the Heat/Cool system for correct operation. If the system operates correctly, replace the thermostat.
Furnace Cycles Too Fast or Too Slow (narrow or wide temperature swing)
|
1.) The location of the thermostat and/or the size of the Heating System may be influencing the cycle rate.
| Digital thermostats normally provide precise temperature control and may
cycle faster than some older mechanical models. A faster cycle rate means the
unit turns on and off more frequently but runs for a shorter time so there is
no increase in energy use. If you would like to increase the cycle time, clip
Jumper W-905 as for Hydronic Heating Systems. It is not possible to shorten
the cycle time. If an acceptable cycle rate is not achieved as received or by
clipping W-905 contact a local service person for additional suggestions.
Thermostat Display & Thermometer Disagree Cooling Cycles Too Fast or Too Slow
(narrow or wide temperature swing)|
1. The location of the thermostat and the size of the Cooling System can influence the cycle rate.
|
The cycle rate for cooling is fixed and can not be adjusted. Contact a local service person for suggestions.
Thermostat Setting and Thermostat Thermometer Disagree| 1. Thermostat
thermometer setting requires adjustment.| The thermometer can be adjusted +/-
3 degrees. See Temperature Display Adjustment in the Operation section.
Blank Display and/ or Keypad Not Responding| 1. Voltage spike or static
discharge.
2. Battery change required.
| Replace batteries and check heat/cool system for proper operation. If a voltage spike occurs use the Reset Operation listed above.
