Step 6. Adjust System On-Time, °F/°C, As Required
The thermostat on-time is factory-set for a warm air, gas or oil heating system. If you are installing it on another type of system, adjust the on-time accordingly by setting screws A and B on the back of the thermostat. Use the heating system table shown in the illustration

In the unlikely event that you want a longer furnace on-time, readjust screws A and/or B as follows: First, turn both screws in completely, then adjust for system type: · Warm Air Furnace--Set at the Hot Water setting (A--out one turn, B--leave in). · Electric Furnace--Leave at the Warm Air Furnace setting (A--leave in, B--leave in). NOTE: This thermostat does not have a setting for steam/gravity air; cycles would not be long enough for accurate temperature control.
IMPORTANT When using a high efficiency furnace such as a 90 percent or greater Average Fuel Utilization Efficiency (AFUE) unit, adjust screw A out one turn and leave screw B in. If readings are desired in degrees Celsius, adjust screw C out one turn.
