IOM Instructions
HBH/V CompaCt
Heat Controller, Inc.
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 Figures 22 through
25c to the low voltage terminal strip on the CXM control
board. Practically any heat pump thermostat will work
with Heat Controller units, provided it has the correct
number of heating and cooling stages.
