Using a thermostat will help you maintain a constant temperature throughout the house. A
fixed wall mounted 24v thermostat is required.
Note: Thermostat manufacturer’s instruction always overrides the information
published in the following section.
Thermostat location
The thermostat must be installed on an inside wall of the house and where it will be the
least affected by affected by air currents from a hot air outlet or cold outside walls. The
thermostat must be installed at a minimum of 55 inches above the floor.
Thermostat wiring
Before installing the thermostat, disconnect the furnace from the outlet. Use a 18 AWG 2
strand wire. Connect the two wires from the thermostat to the terminal at the rear right
side of the furnace. To do this, loosen the two screws in the middle of the terminal bloc and
insert the wires in the terminals. Tighten the two screws. Then open the thermostat
housing and connect the wires following the manufacturer's instructions.
