Mounting
The SZ1024 and SZ1033 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
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 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 mounted in an area which is accessible for adjusting
its settings.
Caution: Remove power from thermostat prior
to mounting.
