Thermostat Installation
Wiring
Refer to equipment manufacturer's instructions for specific system wiring. After wiring, consult the INSTALLER MENU for proper thermostat configuration. The following table describes typical system wiring and thermostat terminal functions:
| Terminal Designations | Terminal Function |
|---|---|
| RC* | Power for Cooling |
| RH* | Power for Heating |
| O/B | Changeover Terminal - Energized in Heat (B) or Cool (O) for Heat Pump or Damper Systems |
| Y** | Cooling Relay |
| G | Fan Relay |
| W** | Heating Relay |
| C | Common wire for 24V (optional with batteries) |
*When both RC and RH wires are present, cut the RC/RH jumper.
**For heat pump systems, add a jumper wire to connect terminals Y and W.
Precautions
- Do not exceed specification ratings.
- All wiring must conform to local and national electrical codes and ordinances.
- This control is a precision instrument; handle carefully to avoid malfunction.
WARNING: Do not use on circuits exceeding specified voltage. Higher voltage can damage the control and pose a shock or fire hazard. Do not short terminals on gas valve or primary control to test; this can burn out the thermostat and cause injury or property damage.
CAUTION: To prevent electrical shock and equipment damage, disconnect electrical power to the system at the main fuse or circuit breaker box until installation is complete.
Switch Settings
- Gas/Elec Switch: Set to Elec for heat pump or electric furnace. Set to Gas for gas or oil furnace.
- O/B Terminal Switch: Factory set to O (energized in Cool). Move to B if the heat pump requires energizing the changeover relay in Heat.
- RC/RH Jumper Wire: This thermostat connects RC and RH terminals by default. If separate RC and RH wires are provided, clip the RC/RH jumper to isolate these terminals.

Heating System
- Set the System Switch to Heat.
- Press ▲ to set the thermostat 1°F above room temperature. The system should start, and "Heat On" should appear on the display.
- Press ▼ to set the thermostat 1°F below room temperature. The heating system should stop, and the display should show "Heat".
Cooling System
- Set the System Switch to Cool.
- Press ▼ to set the thermostat 1°F below room temperature. The blower should start on high speed, followed by cool air. "Cool On" should appear. There may be a 5-minute delay (see Installer Menu, item 50).
- Press ▲ to set the thermostat 1°F above room temperature. The cooling system should stop, and the display should show "Cool".
Note: "Starting Soon" indicates the compressor lockout feature is active, with a delay before compressor operation.
CAUTION: To prevent compressor and property damage, do not operate the cooling system if the outdoor temperature is below 50°F. Ensure compressor oil heaters have been operational for 6 hours and the system has been off for at least 5 minutes before running the compressor.

Troubleshooting
| Symptom | Possible Cause | Corrective Action |
|---|---|---|
| No Heat/No Cool/No Fan | 1. Blown fuse or tripped breaker 2. Furnace power switch OFF 3. Furnace blower compartment door loose 4. Loose connection |
1. Replace fuse/reset breaker 2. Turn switch ON 3. Secure door panel 4. Tighten connections |
| No Heat | 1. System Switch not set to Heat 2. Loose connection 3. Heating system requires service or thermostat replacement |
Verify wire attachments. Diagnostic: Set System Switch to Heat, raise setpoint. Listen for a click and "Heat On" on display within 5 minutes. If no click, reset thermostat. If still no click, contact service. If click occurs, contact furnace manufacturer/service. |
| No Cool | 1. System Switch not set to Cool 2. Loose connection 3. Cooling system requires service or thermostat replacement |
Verify wire attachments. Diagnostic: Set System Switch to Cool, lower setpoint. Follow same diagnostic as "No Heat", but for cooling. Note: A 5-minute delay may occur if compressor lockout is enabled. |
| Heat, Cool, or Fan Runs Constantly | Possible short in wiring, thermostat, or system | Check wire connections for shorts. Reset thermostat. If problem persists, contact HVAC service. |
| Thermostat Display & Thermometer Disagree | Thermostat display requires adjustment | Adjust display +/-5 via User Menu item 04. |
| Furnace/AC Cycles Too Fast or Slow | Thermostat location or heating system size influences cycle rate | Digital thermostats cycle faster. Adjust cycle rate in Installer Menu (items 30 & 35). If issues persist, contact HVAC service. |
| "Call for Service" icon appears | 1. Heating/Cooling system unable to reach setpoint within 2 hours 2. "--" displayed for Room Temperature 3. Buttons not operating |
1. See "No Heat" corrective action. 2. See "No Cool" corrective action. 3. Replace thermostat. 4. Ensure keypad lockout is not enabled. |
Resetting the Thermostat or Thermostat Settings
If the display is blank or unresponsive with good batteries, remove batteries for 2 minutes to reset. Menu settings and programs are retained. If the issue persists, replace the thermostat.
To reset only schedule and user settings to factory defaults, press and hold Menu and Backlight buttons simultaneously until the display goes blank and resets.
