Thermostat Installation
Wiring
Refer to equipment manufacturer’s instructions for specific system wiring information. After wiring, see INSTALLER MENU for proper thermostat configuration. The wiring table below shows typical systems and describes the thermostat terminal functions.
| Terminal Designations | Terminal Function |
|---|---|
| R | Power (24V) |
| O/B | Changeover Terminal-Energized in Cool (O) or Heat (B) for Heat Pump or Damper Systems |
| Y | Heat and Cool Mode 1st Stage Compressor |
| G | Fan Relay |
| E* | Auxiliary only Heat Mode (Emergency Heat) |
| C | Common wire for 24V (optional with batteries) |
| L | Heat Pump malfunction / Diagnostic terminal (input signal requires common) |
| W2* | Heat Mode – 2nd stage |
*Cut W2/E jumper when separate heat sources are used for W2 and E.
IMPORTANT: For Dual Fuel Heat Pump applications, be sure to turn on the Duel Fuel Logic option (found in the Installer’s Menu).
Leveling Thermostat: Leveling is for appearance only and will not affect thermostat operation.
Precautions
- Do not exceed the specification ratings.
- All wiring must conform to local and national electrical codes and ordinances.
- This control is a precision instrument, and should be handled carefully. Rough handling or distorting components could cause the control to malfunction.
WARNING: Do not use on circuits exceeding specified voltage. Higher voltage will damage control and could cause shock or fire hazard. Do not short out terminals on gas valve or primary control to test. Short or incorrect wiring will burn out thermostat and could cause personal injury and/or property damage.
CAUTION: To prevent electrical shock and/or equipment damage, disconnect electrical power to system, at main fuse or circuit breaker box, until installation is complete.
Battery Location
Premium AA alkaline batteries are required when a C-wire is not available. When a C-wire is available, the batteries provide a back-up source of power, which will maintain the clock in the event of a power outage.
W2/E Jumper Wire
This thermostat electrically connects the W2 and E terminals, eliminating the need for a jumper wire. If your system has separate W2 and E wires, clip the W2/E jumper located on the back of the thermostat to isolate both terminals for independent use.
O/B Terminal Switch
The O/B switch is factory set to the 'O' position, accommodating most heat pump applications that require the changeover relay to energize in Cool. If your heat pump requires the 'B' terminal to energize the changeover relay in Heat, move the O/B switch to the 'B' position.
Installer Menu
The Installer Menu provides access to all system performance options, while the User Menu offers access to settings that do not affect system performance. To access the Installer Menu, press and hold the Menu button for 8 seconds. The display will show item 30. Use the Next and Back buttons to navigate through menu items. Press the ▲ or ▼ buttons to change a setting.

Troubleshooting
| Symptom | Possible Cause | Corrective Action |
|---|---|---|
| No Heat/ No Cool/ No Fan (common problem) |
1.) Blown fuse or tripped circuit breaker | 1.) Replace fuse or reset breaker. |
| 2.) Furnace power switch to OFF | 2.) Turn switch to ON. | |
| 3.) Furnace blower compartment door panel loose or not properly installed | 3.) Replace door panel in proper position to engage safety interlock or door switch. | |
| 4.) Loose connection to thermostat or system | 4.) Tighten Connections. | |
| No Heat | 1.) System Switch not set to Heat | Verify thermostat and system wires are securely attached. Diagnostic: Set System Switch to Heat and raise the setpoint above room temperature. Within five minutes, the thermostat should make a soft click sound and "Heat On" should appear on the display. This sound 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 system is operating correctly. |
| 2.) Loose connection to thermostat or system | Verify thermostat and system wires are securely attached. | |
| 3.) Heating System requires service or thermostat requires replacement | See diagnostic steps above. | |
| No Cool | 1.) System Switch not set to Cool | Verify thermostat and system wires are securely attached. Diagnostic: Set System Switch to Cool and lower setpoint below room temperature. 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 if the compressor lock-out option is selected in the installer menu (see INSTALLER MENU, item 50). |
| 2.) Loose connection to thermostat or system | Verify thermostat and system wires are securely attached. | |
| 3.) Cooling System requires service or thermostat requires replacement | See diagnostic steps above. | |
| Heat, Cool or Fan Runs Constantly | Possible short in wiring, thermostat, heat, cool, or fan system. | Check each wire connection to verify they are not shorted or touching other wires. Try resetting the thermostat. If the condition persists, contact your HVAC service person. |
| Thermostat Display & Thermometer Disagree | Thermostat display requires adjustment. | Display can be adjusted +/-5°. See User Menu item 04. |
| Furnace (Air Conditioner) Cycles Too Fast or Slow (narrow or wide temperature swing) | The location of the thermostat and/or the size of the Heating System may be influencing the cycle rate. | Digital thermostats provide precise control and cycle faster than older mechanical models. The system turns on and off more frequently, but runs for a shorter time. If you would like to increase cycle time, choose SLO for slow cycle in the Installer menu (Reference menu items 30 & 35). If an acceptable cycle rate is not achieved, contact your HVAC service person. |
| "Call for Service" icon appears on display | 1.) Heating system is not able to heat the space to within 10 degrees of the setpoint within 2 hours. 2.) Cooling system is not able to cool the space to within 10 degrees of the setpoint within 2 hours. 3.) If "--" is displayed for the Room Temperature, a replacement thermostat is needed. 4.) None of the buttons operate on the thermostat. 5.) If "Call for Service" is flashing, compressor self-diagnostic is detecting an issue with the outdoor unit. |
1.) See corrective action for "No Heat". 2.) See corrective action for "No Cool". 3.) Replace thermostat. 4.) Make sure keypad lockout is not turned on (denoted by ?). 5.) Contact a service person to verify the equipment is operating correctly. |
Resetting the Thermostat or Thermostat Settings
If the thermostat has good batteries but has a blank display or does not respond to key presses, reset it by removing the batteries for 2 minutes. This reset will not change menu settings or programs. If the condition persists after reinstalling the batteries, replace the thermostat.
To conveniently reset only the schedule and user settings back to factory defaults, press the Menu and Backlight buttons simultaneously and hold until the display goes blank and resets.
