How do I install the thermostat on my wall?

First, turn off power at the breaker box. Position the UWP mounting system level on the wall, mark and drill holes, then insert wall anchors. Insert wires through the wiring hole, mount the UWP, and tighten the mounting screws until secure. Finally, attach the thermostat by aligning it with the UWP and pushing gently until it snaps in place, then restore power. (Page 1 — Setup Instructions)
