TROUBLESHOOTING
Possible Cause
Corrective Action
Symptom
5. Heating system requires service or
thermostat requires replacement.
Diagnostic: Press SYSTEM button to HEAT and
raise the setpoint above room temperature. Within a
few seconds 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,
contact the furnace manufacturer or a service
person to verify the heating is operating correctly.
No Heat (continued)
No Cool
1. SYSTEM button not pressed to COOL. Press SYSTEM button to COOL and lower setpoint
below room temperature.
2. Loose connection to thermostat or
system.
Verify thermostat and system wires are securely
attached.
3. Cooling system requires service or
thermostat requires replacement.
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.
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 above. 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.
1. Possible short in wiring.
2. Possible short in thermostat.
3. Possible short in heat/cool/fan
system.
Heat, Cool or Fan
Runs Constantly
4. FAN Switch set to Fan On.
Digital thermostats normally provide precise
temperature control and may cycle faster than some
older mechanical models. A faster cycle rate means
the unit turns on and off more frequently but runs for
a shorter time so there is no increase in energy use.
If you would like to increase the cycle time, choose
SL for slow cycle in the menu, step 4. If an accept-
able cycle rate is not achieved as received or by
choosing slow cycle, contact a local service person
for additional suggestions.
1. The location of the thermostat and/or
the size of the Heating System may
be influencing the cycle rate.

The thermometer can be adjusted +/- 4 degrees.
See Temperature Display Adjustment in the
