Step 3. Mount the thermostat on the wall
There are two sets of mounting holes – one set for use when mounting to a
junction box, another set for direct wall mounting.
IMPORTANT! TURN OFF POWER AT THE HVAC EQUIPMENT BEFORE
PROCEEDING WITH THERMOSTAT INSTALLATION!
Mounting the thermostat directly to the wall (without junction box)
1. Place the thermostat wire opening over the wall opening. If replacing a
thermostat, place the thermostat to cover the old thermostat silhouette.
The base of the thermostat is raised to allow for wire routing behind the
thermostat.
2. Level the thermostat (for appearance only) and mark the mounting hole
locations.
3. Drill a 3/16” dia. hole at the marked locations and install drywall anchors
(included). Drywall anchors should be used unless installing on paneling
or other hard surfaces. Anchors should be flush with the wall surface.
4. Secure the thermostat to the wall using two (2), #8 x 1-1/2” long pan head
screws (included).
