from the rear cover, simply grasp the front and back of the thermostat firmly and pull

apart.

Attach the rear of the thermostat to the wall using the included Plastic Anchors.

Position the rear cover so that the wires can be fed through the rectangular opening

in the back of the thermostat. Then mark the locations of the mounting points on the

wall. Drill a 3/16” hole for each anchor. Insert the anchors into the wall and attach the

rear cover using the included screws. The thermostat can also be mounted to an

electrical box using the included machine screws.
