You can choose from three methods to power the thermostat:

• Batteries only (AAA alkaline).

• 24 Vac direct connection only.

• 24 Vac direct connection with battery backup (AAA alkaline).

• Single-Transformer System—Connect the common side of 

the transformer to the C screw terminal of the thermostat 

wallplate. Leave the metal jumper wire in place between Rc 

and R.

• Two-Transformer System—Connect the common side of 

the cooling transformer to the C screw terminal of the 

thermostat wallplate. Remove the metal jumper wire 

between Rc and R.

1. Install two AA alkaline batteries on the back of the ther-

mostat as marked. See Fig. 23.

2. Locate and remove tab labeled Remove. See Fig. 24.

Locate and mount the sensor in the same fashion as the 

thermostat. See the Select Thermostat Location section.

Consider the following as well:

1. Be sure wire distance between sensor and thermostat is 

less than 200 feet.

2. Mark the area on the wall selected for mounting the 

sensor or junction box.

3. Sensor wire must be separate from the thermostat cable.

4. Run wire cable to a hole at the selected wall location.

5. Pull approximately three inches of wire through the 

opening.

NOTE: Color-coded, 18-gauge wire is recommended.
