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 due to air in

fi

 ltration through the 

wall cavity. 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 or larger wire. 
Wire the appropriate thermostat as shown in Figures 28a and 
28b to the low voltage terminal strip on the DXM2 control 
board.  Practically any heat pump thermostat will work with 
these units, provided it has the correct number of heating 
and cooling stages. However, using the communicating 
thermostat (ATC32U**) is highly recommended for on-site, 
easier con

fi

 guration, monitoring and diagnosis.

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 pump. Use ATC32U**.
4) Only use ATC Communicating Thermostat when using Humidifier (H Input) with 
 

units with internal flow controller.
