Mounting

The SZ1009 is designed for wall mounting using two
#6-32 machine screws sheet metal screws, either over
a horizontally installed 2" x 4" junction 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.
