Mounting Plate

1. Carefully pull the labeled wires through the center hole in the Mounting Plate.

2. Position Thermsotat for best appearance to cover the hole in the wall.

3. Mark first and drill a 1⁄4 in. (6mm) hole at each screw location.

4. If you are mounting the Thermostat to sheet rock or if you are using the old mounting holes, use the

plastic anchors provided.

5. Attach the Mounting Plate to the wall with the screws provided.
