Mounting
The SZ1063 and 64 are designed for wall mounting using two #6
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 approxi-
mately 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.
