Step 4. Set the thermostat for your type of heating system Fig. 8 IMPORTANT: Setting your thermostat correctly for your type of heating system allows it to maintain accurate temperature control, minimize swings in the temperature of the room, and efficiently run the fan.
Heating System Table Note: Setting the screw “out one turn” means turning the screw 360° counter-clockwise, or one complete turn. Type of system Screws A and B Fuel switch Warm air, gas, or oil heating system with an efficiency rating under 90%. (The furnace efficiency rating should be on the furnace.
Step 6. Mount the thermostat Fig. 11 Fig. 12 a. Align the tabs at the top of the thermostat with the tabs at the top of the mounting plate (Fig. 11). b. Press the lower edge of the case to latch the bottom of the thermostat (Fig. 12). M20131 M20130 Step 7.
