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 infiltration 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 thermostat as shown in Figure 22 to the low
voltage terminal strip on the EXM control board. The AWC
communicating thermostat provides simple configuration,
monitoring and diagnosis.
