Installation
Avoid mounting in areas where acid fumes or other deteriorating
vapors can disintegrate the metal parts of the module’s circuit
board, or in areas where escaping gas or other explosive vapors are
present.
You must mount the sensor in a position that will allow for proper
clearance for installation, servicing, wiring, and removal.
Using the dimensions as a reference, mount the Temperature and
Humidity Sensor on the outside of the dampers to measure outside
temperature and humidity, or inside the return air duct to measure
the return temperature and humidity. If mounted outside, the sensor
must be placed within hood behind the outdoor air fi lter. It needs to
be protected from direct exposure to water (snow/rain) and direct
exposure to sunlight (UV radiation).
The orientation of the sensor is critical to ensure optimal
performance. (Please see fi gures on recommended orientation.)
Ensure installation matches an approved orientation before securing
with #8 self-tapping screws (included in kit).
The electrical connection needs to be wired using appropriate
insulated spade connectors, ¼” female, according to the wiring
diagram.
