Part I: Install the wallPlate
1. Position the wallplate on the wall with the directional arrow pointing up (see Fig. 3) and
terminal blocks facing outward.
2. Pull equipment wires through the wallplate wiring passage (see Fig. 3).
3. Use a level to determine the best horizontal wallplate mounting position.
4. Mark positions of the screw holes (two at minimum) with a pencil and remove wallplate.
5. Drill holes at pencil-marked locations (3/16” for drywall, 7/32” for plaster).
6. Insert the wall anchors in the holes, tapping them into place.
7. Mount the wallplate onto the wall and insert screws through mounting holes. Assure
that all loose wires come through the center opening of the backplate (see Fig. 3).
8. Cap off any unused wires and terminate properly according to local building codes.
Part II: attach wIres to thermostat wallPlate
1. Select the terminal designations that correspond to the system type (see Table 1).
