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.
