Mounting
The SZ1009, SZ1022, SZ1031 and SZ1035 are designed for
wall mounting using two #6 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 inte-
rior wall which reflects normal room environment, at a height
of approximately five feet from the floor. Avoid areas
exposed to direct sunlight, unusual heat sources, open doors
and windows, or unventilated locations.
If using a remote room sensor, it should be mounted in the
manner described above. The thermostat may then be mount-
ed in an area which is accessible for adjusting its settings.
Caution: Remove power from thermostat prior to
mounting.
