TROUBLESHOOTING

	SYMPTOM	POTENTIAL SOLUTION
Thermostat does not turn on heating or cooling system.		Check to see if OFF is shown in display. This indicates that the system is turned off at the thermostat. Move the system selector switch to the HEAT or COOL position. After the compressor short cycle protection 5-minute period expires, the system should start within a minute. Compressor protection features may be in effect due to compressor short cycle conditions. See Compressor Protection section for full explanation of this feature.
Thermostat turns on heating instead of cooling or cooling instead of heating.		Check thermostat wiring to make sure that the heating and cooling stages are connected to the correct terminals on the wiring terminal block. See Installation and Wiring Diagram sections of this manual.
Thermostat turns heating or cooling system on too often or not often enough.		Increase or decrease first stage temperature differential setting as appropriate to provide the desired performance level. See Setting Temperature Differential and Residual Cooling Fan Feature section of this manual.
Thermostat turns on second (auxiliary) stage of heating or cooling too quickly or not quickly enough.		Increase or decrease second (auxiliary) stage temperature differential setting as appropriate to provide the desired performance level. See Setting Temperature Differential and Residual Cooling Fan Feature section of this manual.
OFF is shown in thermostat display and heating or cooling system will not start.		This indicates that the system is turned off at the thermostat. Move the system selector switch to the HEAT or COOL position. After the compressor short cycle protection 5-minute period expires the system should start within several seconds.

	SYMPTOM	POTENTIAL SOLUTION
Thermostat display is blank.		It is possible that AC power is not present at the thermostat. Check fuse, circuit breaker and thermostat wiring as appropriate to verify AC power is available. If AC Power is present, call a professional service technician immediately to verify thermostat and system performance.
HI is shown in the thermostat display where the room temperature is normally displayed.		The temperature sensed by the thermostat is higher than the 90˚ F (32˚ C) upper limit of the thermostats display range. The display will return to normal after the sensed temperature lowers within the 45˚ to 90˚ F (7˚ to 32˚ C) display range. Turn on the cooling system or use other methods to lower the temperature accordingly. This condition could occur from the system being turned off during an exceptionally warm period or upon installation when the thermostat has been stored for a long period of time in a warm vehicle or location prior to being installed. The thermostat is equipped with a mechanical high temperature safety switch that will turn off the thermostat should the temperature exceed 99˚ F (37˚ C).
LO is shown in the thermostat display where the room temperature is normally displayed.		The temperature sensed by the thermostat is lower than the 45˚ F (7˚ C) lower limit of the thermostats display range. The display will return to normal after the sensed temperature rises within the 45˚ to 90˚ F (7˚ to 32˚ C) display range. If the temperature in the controlled space seems to be normal, wait for the thermostat to acclimate to the correct room temperature. If the room seems to be colder than usual, turn on the heating system to raise the temperature as needed for comfort within the room. This condition could occur from the system being turned off during a cold weather period or upon installation when the thermostat has been stored for a long period of time in a cold vehicle or location prior to being installed. The thermostat should be allowed to warm up prior to installation to allow proper heating control once installed.
Thermostat will not allow me to program a setpoint temperature higher than 90˚ F (32˚ C).		This is above the normal thermostat temperature setting range of 45˚ to 90˚ F (7˚ to 32˚ C).
Thermostat will not allow me to program a setpoint temperature lower than 45˚ F (7˚ C).		This is below the normal thermostat temperature setting range of 45˚ to 90˚ F (7˚ to 32˚ C).
Fan continues to run all the time whether the system is on or off.		Check that the fan control switch is in the AUTO position. This will allow the fan to run only when the heating or cooling system is turned on and running. Check thermostat wiring to make sure that the fan control wiring is connected to the correct terminals on the wiring terminal block. See Installation and Wiring Diagram sections of this manual.

	SYMPTOM	POTENTIAL SOLUTION
Fan continues to run in cooling mode when the system has turned off.		The Residual Cooling Fan Control Feature can allow up to a 90 second fan delay after cooling system shutdown for energy efficiency gains. The default setting is 60 seconds. This can be changed to disable this feature or shorten the time period if desired. See Setting Residual Cooling Fan Feature section of this manual.
The room is too warm or too cold.		See Review Set Temperature section of this manual to verify the current setpoint and make any modifications that are necessary.
Thermostat will not allow me to change the setpoint.		Keypad is locked. Press either the or key along with the backlight key to unlock.
Fan runs intermittently or when system is off.		Fan switch is in the Recirculate Mode  ®.
