CAUTION
Loss of internal programs
may result from static
discharge to thermostat
circuit board. Avoid
touching the circuit board
and touch a grounded
metal object before
handling the thermostat.
(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.
CAUTION
Minimize wire entry hole size and seal the hole – drafts from inside the wall could affect temperature readings.
