Option
Mount the thermostat in the largest
space occupied by the most people for
the best average temperature sensing.
The thermostat should be mounted about
5 feet from the floor in contact with freely
circulating air, but not with major drafts.
Avoid the following areas:
• Behind doors or in corners where ther is
no free circulation.
• Locations where the sun’s rays or
infrared radiation from appliances or
fireplaces may affect thermostat
operation.
• Surfaces subject to vibration.
• On walls that contact outside air.
• Adjacent to or in line with conditioned air
discharge grilles or doorways.
Remote Mounted Thermostat Wiring
After the thermostat is mounted, wire the
thermostat back to the unit control panel
according to the correct diagram shown
on inside of panel door.
The total resistance of the thermostat and
the control wiring to each terminal must
not exceed 1 ohm. Table I-PR-6 provides
recommended wire sizes for length of
run.

SCRG
The SCRG/SIRG air-cooled condenser
should be wired to the control panel of
the SCRG/SIRG unit to ensure proper
system operation. Reference unit wiring
