 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 17a-b 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.

Dehumidification

Notes:

Auxiliary Heat

1) ECM automatic dehumidification mode operates with dehumidification airflows 

  in the cooling mode when the dehumidification output from thermostat is active. 

  Normal heating and cooling airflows are not affected.

2) DXM2 board DIP switch S2-7 must be in the auto dehumidification mode for 

  automatic dehumidification.

3) DH connection not possible with units with internal variable speed pump. Use ATC32U03C.

4) Only use ATC Communicating Thermostat when using Humidifier (H Input) in 

  units with internal variable speed pump.
