Outdoor Temperature Sensor Installation
Guidelines
• Avoid areas with direct sunlight and where
temperatures may not be representative of true
outdoor temperature.
• Avoid placing sensor in close proximity of heat
sources that may affect correct temperature
sensing. (fans, exhausts, vents, lights)
• Avoid installing the sensor in areas where the
sensor is subjected to excessive moisture.
• 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.
• If the system requires a fixed operating
temperature, the outdoor sensor is not required
and should not be installed.
There is no connection required if an outdoor
sensor is not used in the installation.
• Use a minimum 22 AWG wire for runs of 100 ft or
less and minimum 18 AWG wire for runs of up to
150 ft.
• Mount the outdoor sensor on an exterior surface
of the building, preferably on the North or
Northeast side, in an area that will not be affected
by direct sunlight or will be exposed to varying
weather conditions.
• For correct mounting procedures, follow
instructions provided with the sensor.
• If sensor wires are located in an area with sources
of potential electromagnetic interference (EMI),
the sensor wires should be shielded, or the wires
routed in a grounded metal conduit.
If using shielded cable, the shielding should
be connected to the common ground of the
appliance.
