15 WALLPLATE (Included with thermostat.) Provides mounting base and wiring connections for heating-only or cooling-only thermostat. 16 SUBBASE (Optional, not included with thermostat; ordered separately.) Provides mounting base, wiring connections and manual switching control for heating/cooling thermostat. See Setting Subbase Switches section for additional information.
Setting the Temperature For Heating: Set the left lever (blue mark) to the energy saving temperature you want when you are sleeping or your home is unoccupied. Set the right lever (red mark) to the tempera- ture you want for normal comfort periods. NOTE: You may override the time program by setting both the red and blue levers to the same temperature setpoint.

temperature (comfort period); a blue pin is inserted at 10:00 PM for low temperature (energy saving period). Two additional sets of pins are located in the program pin storage area. You can set up to six temperature changes with the pins supplied. We recom- mend at least five hours for each energy saving period.

ON—Fan operates continuously. AUTO—Fan operates with cooling equipment as controlled by the thermostat or with the heating equipment as controlled by the plenum fan switch. In electric heat, heat pump and fan coil systems, the fan is controlled by the thermostat in heating and cooling.
Troubleshooting Your Honeywell thermostat requires little or no attention. Most problems can generally be traced to the following. Problem Check No heat. — System switch may be in OFF or COOL position. — Fuse or circuit breaker. — Furnace power switch may be OFF.

— Filter may be clogged. Safety limit on equipment can cut off power to system. Action Remove thermostat from the wallplate or subbase and measure the voltage. Refer to Voltage at Timer Terminals table for cause and reaction. Push down on pins to make sure they are completely seated in program dial.

The equipment should cycle on and off just enough to keep the room temperature close to the temperature lever settings. If the thermostat seems to cycle the heating system too fast or too slow, adjust the cycle rate by moving the anticipator setting lever one indicator mark at a time (Fig.
Remove thermostat cover and open the flip-up cover. Set the thermostat cover on a table near a thermometer of known accuracy. Allow at least five minutes for cover thermom- eter to sense area temperature; then compare the readings.
