THE SMART SOLUTION FOR ENERGY EFFICIENCY
Electrical – Thermostat Wiring
Thermostat Installation - The thermostat should be
located on an interior wall in a larger room, away from
supply duct drafts. DO NOT locate the thermostat in areas
subject to sunlight, drafts or on external walls. The wire
access hole behind the thermostat may in certain cases
need to be sealed to prevent erroneous temperature
measurement. Position the thermostat back plate against
the wall so that it appears level and so the thermostat
wires protrude through the middle of the back plate. Mark
the position of the back plate mounting holes and drill
holes with a 3/16” (5mm) bit. Install supplied anchors
and secure plate to the wall. Thermostat wire must be 18
AWG wire. Representative thermostat wiring is shown in
Figures 21 however, actual wiring connections should be
determined from the thermostat IOM and or unit wiring
diagram. Practically any heat pump thermostat will work
with ClimateMaster units, provided it has the correct
number of heating and cooling stages.
