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. Wire the appropriate thermostat as shown in Figure 24 or 25 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 (7602-443) is highly recommended for on-site, easier configuration, monitoring and diagnosis. An optional outdoor temperature sensor is available.

The 7602-452 sensor is a thermistor, used as an accessory for thermostat model 7602-443. This sensor provides outdoor air temperature information for the control system, as well as an indication of outdoor temperature on the display screen.
