Troubleshooting Guide • Homeowner Manual

Blank Display and/or Keypad Not Responding

Possible Cause

Corrective Action

Voltage spike or static
discharge.

Use the Reset Operation described on page 17.

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 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
Contact your installing contractor to have the

cycle rate adjusted and additional suggestions.

Thermostat Setting and Thermometer Disagree

Possible Cause

Corrective Action

Thermostat
thermometer setting
requires adjustment.

The thermometer can be ad/- 5 degrees.

See Temperature Display Adjustment on page 15.
