Outdoor Temperature Sensor Installation Guidelines
Avoid areas with temperature uctuations by direct sunlight,
and where the temperature may not be representative of true
outdoor temperature.
Best location to install the temperature sensor is on a North or
Northeast side of a structure under eaves where the sensor is
shielded from direct sunlight.
Avoid placing sensor in close proximity of heat sources that
may a ect correct temperature sensing. (fans, exhausts, ues,
lights)
Avoid installing the sensor in areas where the sensor is
subjected to excessive moisture.
Use 18 gauge wiring (thermostat wiring) with no splices.
(except at the unit harness connection with yellow leader
wire.)
Caution should be taken to avoid potential electromagnetic
interference (EMI) by routing separately from potential
sources such as line voltage wiring. When necessary, shielded
cable may be used.
Make sure wiring connections are secure before closing the
cap.
The sensor is a water resistant device.
Any damage to the device may require the replacement of the
entire component.
