Troubleshooting
No Heat
Possible Cause Corrective Action
Pilot light not lit. If it will not stay lit, call for service from your HVAC
contractor.
System switch not set to HEAT. Press the thermostat’s
SYSTEM
button one or
more times to select HEAT and press to raise the
temperature setpoint above room temperature.
Furnace Lock-Out Condition. Heat may also be
intermittent. Many furnaces have safety devices that shut down
when a lock-out condition occurs. If the heat works
intermittently, contact the furnace manufacturer or
your HVAC contractor for assistance.
Heating system requires service or thermostat
requires replacement.
To diagnose this condition:
Press SYSTEM button to select HEAT and press
to raise the temperature 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 after being reset,
contact Delmarva Power Energy Wise Rewards for a
replacement thermostat. If the thermostat does click,
contact the furnace manufacturer or your HVAC
contractor for a service visit to verify the heating is
operating correctly.
Furnace (Air Conditioner) Cycles Too Fast or Too Slow (Narrow or Wide Temperature Swing)
Possible Cause Corrective Action
The location of the thermostat and/or the size of the
heating system may be influencing the cycle rate. Electronic thermostats, like this one, 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 to maintain the desired temperature, but
runs for a shorter time so there is no increase in
overall energy use.
