b. Run the wiring from the heater to the thermostat.
c. Remove the thermostat front cover and connect the wires to thermostat terminals A and B.
d. Ensure the thermostat batteries are correctly installed and mount the thermostat level on the wall (refer to, and

25 for BX5).
g. For fan-only operation, wire a switch in circuit between heater terminals R and G.
