You can remove the temporary setting at any time by pressing RUN, the system will return to your previous programmed schedule. Note: Pressing the p or q button once will turn on the backlight.
OVERRIDING SCHEDULES PERMANENTLY Press HOLD to override the programmed schedule. All programmed temperature changes for all periods will be ignored. You can remove the hold at any time by pressing RUN, the system will return to your previous programmed schedule. While the system is in hold you can manually change the temperature at any given time by pressing p or q. The thermostat will maintain this temperature change until you manually change it again or remove the hold. “Hold.
TURNING OFF SCHEDULES Press HOLD for five seconds until the manual indicator “man.” appears on the screen. Your thermostat now functions as a nonprogrammable device with no scheduled program. SET, RUN, and HOLD will not work while in this setting. If it is too hot or too cold, you will have to manually change the temperature. Press p or q to raise or lower the temperature.
BUILT IN COMPRESSOR PROTECTION This function helps protect against damage to the compressor in your air conditioning or heat pump system. The compressor is forced to wait five minutes after turning off before it can turn on again. The appropriate MODE indicator icon will flash on the display whenever this feature is running. / flashes while minimum off time is being enforced.
EARLY START FUNCTIONALITY THERMOSTAT CARE This function allows the heating or cooling system To prevent damage to the clear lens over the to turn on before the programmed start time thermostat face, use a soft cotton cloth and so that the room temperature matches the set clean with mild soap and water only. temperature at the start time. DO NOT use paper towels or other abrasive Example: Your Wake time is set for 6:30 am with a cloths. DO NOT spray any liquid directly temperature of 72°.
REPLACING THE BATTERIES It is recommended that the batteries in the thermostat be replaced once a year or before leaving the home for a prolonged period of time. 1. Switch the system MODE to off before changing the batteries. 2. Remove the thermostat body from its base by gently pulling them apart. 3. Turn the thermostat over and remove old batteries. 4. Replace them with fresh Energizer® or Duracell® alkaline AAA batteries, carefully observing the required polarities. 5.
TROUBLESHOOTING Problem: No heating/cooling system activation Solution: 1. Verify MODE switch is in proper heat or cool mode. 2. Check batteries. Replace if necessary. (See “Replacing the Batteries,” page 31). 3. Check set temperature. Set temperature should read above room temperature in heat mode and below room temperature in cool mode. 4. Verify Heating/Cooling power switch isn’t off. 5. Verify that the circuit breaker isn’t tripped. 6. Verify that the furnace door is closed securely. 7.
TROUBLESHOOTING Problem: No fan/fan runs continuously Solution: 1. If the fan runs continuously, verify that the thermostat is in the AUTO position not the ON position. 2. Let the thermostat sit (do not touch) for 30 minutes to allow the temperature to stabilize. 3. Verify that the G wire in the thermostat wiring terminal is connected properly. 4. Verify Heating/Cooling power switch isn’t off. 5. Verify that the circuit breaker isn’t tripped. 6. Verify that the furnace door is closed securely. 7.
TROUBLESHOOTING Problem: Incorrect room temperature Solution: 1. Let the thermostat sit (do not touch) for 30 minutes to allow the temperature to stabilize. 2. Check placement of thermostat; make sure it’s not in an unusually drafty or heated area. 3. Verify that the wall hole for wires is insulated properly. 4. Check Temperature Offset (see “Temperature Offset,” page 16).
TROUBLESHOOTING Problem: Not reaching set temperature Solution: 1. Verify that the MODE switch is in proper heat or cool mode. 2. Verify that Heating/Cooling systems are working properly. (See “No heating/cooling system activation,” page 32.) 3. Check for loose or crossed wiring in the thermostat wiring terminal. 4. Check Temperature Offset (see “Temperature Offset,” page 16). 5. Check placement of thermostat; make sure it’s not in an unusually drafty or heated area. 6.
TROUBLESHOOTING Problem: Temperature does not change at programmed start time for a given period Solution: 1. Verify that the HOLD feature is not active (see “Overriding the Schedules Permanently,” page 27). 2. Check the programmed schedule (see “Modifying the Programmed Schedule,” page 24). 3. Verify that the thermostat is not in MANUAL mode (see “Turning Off Schedules,” page 28). Problem: Heat/cool system doesn’t respond immediately Solution: 1.
TROUBLESHOOTING Problem: Set temperature is 10°F above (in cool mode) or 10°F below (in heat mode) desired temperature Solution: Check batteries. Replace if necessary (see “Replacing the Batteries,” page 31). Problem: System turns on too frequently Solution: The Orbit Clear Comfort™ Pro thermostat uses smart logic to turn on once every cycle period to maximize comfort and temperature stability. To adjust the cycle period, see “Minimum Cycle Period Adjustment,” page 18.
