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.

Possible Cause Corrective Action

Thermostat

thermometer setting
