Mounting System installation” on next page.
Use the Optional Cover Plate when you need to cover
paint gaps from the old thermostat.
1. Before starting, turn the power off at the breaker box
or switch.
2. Mount the Cover Plate to the wall using any of the 6
screw holes. Insert and tighten the mounting screws
supplied with the Cover Plate. Do not overtighten. See
Figure 1. Make sure the Cover Plate is level.
3. Attach the UWP by hanging it on the top hook of the
Cover Plate and then snapping the bottom of the
UWP in place. See Figure 2.
4. If mounting to a wall with no existing wall anchors:
a. Position the Cover Plate on wall. Level and mark
hole positions. See Figure 1.
b. Drill holes at marked positions, and then lightly
tap supplied wall anchors into the wall using a
hammer.
• If your box contains red anchors, drill 7/32” (5.6 mm) holes.
