Symptom
Possible Cause
Correction Action
No Heat/No Cool/No Fan
(common problems)
1. Blown fuse or tripped circuit breaker.
2. Furnace power switch to OFF.
3. Furnace blower compartment door or
panel loose or not properly installed.
4. Loose connection to thermostat or
system.
Replace fuse or reset breaker.
Turn switch to ON.
Replace door panel in proper position to engage safety
interlock or door switch.
Tighten connections.
No Heat
1. Pilot light not lit.
2. Furnace Lock-Out Condition. Heat
may also be intermittent.
Re-light pilot.
Many furnaces have safety devices that shut down when
a lock-out condition occurs. If the heat works intermittently
contact the furnace manufacturer or local HVAC service
person for assistance.
3. Heating system requires service or
thermostat requires replacement.
Diagnostic: Set SYSTEM Switch 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 HVAC service
person to verify the heating is operating correctly.
No Cool
1. Cooling system requires service or
thermostat requires replacement.
Same 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.

Thermostat Setting &
Thermostat Thermometer
Disagree
1. Thermostat thermometer setting
requires adjustment.
The thermometer can be adjusted +/- 4 degrees. See
Temperature Display Adjustment in the Configuration Menu
section.
Furnace (Air Conditioner)
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.
Digital thermostats provide precise control and cycle faster
than older mechanical models. The system turns on and off
more frequently but runs for a shorter time so there is no
increase in energy use. If you would like an increased cycle
time, choose SL for slow cycle in the Configuration menu,
step 6 (heat), 7 (cool) or 8 (heat pump). If an acceptable
cycle rate is not achieved, contact a local HVAC service
person for additional suggestions.
