Mounting
The SZ1022, SZ1031, and SZ1035 are designed for wall
mounting using two #6-32 machine screws sheet metal
screws, either over a horizontally installed 2” x 4” junc-
tion box, or directly to block or drywall.
For best results, the thermostat should be mounted on
an interior wall which reflects normal room environment,
at a height of approximately five feet from the floor.
Avoid areas exposed to direct sunlight, unusual heat
or cool sources, open doors and windows, unventilated
locations and hot or cold air from diffusers.
If using a remote room sensor, it should be mounted in
the manner described above. The thermostat may then
be mounted in an area which is accessible for adjusting
its settings.
Caution
: Remove power from thermostat prior to
mounting.
