CLIMATEMASTER WATER-SOURCE HEAT PUMPS
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 19
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 heat pump units, provided
it has the correct number of heating and
cooling stages.
