WARNING: Do not connect this thermostat to any
electrical source! Electrical shock and/or fire hazard
will occur.
1. Remove jumper wire from control valve (see Figure 26, page 17).
2. Connect one terminal of 25 ft. wire to the "TH" terminal on
the control valve. Connect the other terminal to the "THTP"
terminal on the control valve. See Figure 31.

such as lamps, direct sunlight, fireplace, or heat and air condi-
tioning ducts.
4. Gently remove the cover of the thermostat from the base. Grasp
the sides of the cover firmly and pull to separate from the base.
5. Feed the electrical wires through the rectangular slots on each
side of the base (see Figure 32).
WARNING: Do not connect the thermostat to a
power source. Electrical shock and/or a fire hazard
will occur.
6. Connect one bare wire end to each terminal ("W" and "R") of
