Set System Switch to Heat and raise setpoint above room temperature.

Verify thermostat and system wires are securely attached.

Diagnostic: Set System Switch to Heat and raise the setpoint above room temperature. Within a five minutes 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 above. 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, con- tact the furnace manufacturer or a service person to verify the heating system is operating correctly.

2. Loose connection to thermostat or
system.
3. Cooling System requires service or

Set System Switch to Cool and lower setpoint below room temperature.

Verify thermostat and system wires are securely attached. Same procedure 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 configuration menu (Item 4).

Heat, Cool or Fan Runs Constantly

1. Possible short in wiring.
2. Possible short in thermostat.
3. Possible short in Heat/Cool/Fan

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 below. 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.

Cooling Cycles Too Fast or Too Slow (narrow
