(3) MOUNT THE THERMOSTAT BASE TO THE WALL

1.Place the wire opening in the base over the wire entry hole in the wall. Level the base (for appearance only) and mark the screw locations. See Figure 4.

2.Use the supplied screws and wall anchors to mount the thermostat to the wall. It is recommended that wall anchors be used for installation to drywall/sheet rock.

•Drill a 3/16" hole for wall anchors.

•Drill a 3/32" starter hole for screws only.

3.For junction box mounting, screws are field supplied. The thermostat can be installed on a vertical j-box.

4.Seal the wire entry hole(s) with caulk, drywall putty or insulation to prevent drafts from inside the wall cavity from affecting thermostat performance.
