Mounting

The SZ1017N is 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 SZ1017N should be mounted on an interi-

or 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 win-

dows, or unventilated locations.

If using a remote room sensor, it should be mounted in the

manner described above. The thermostat may be mounted in

an area which is accessible for adjusting its settings.
