DETERMINE LOCATION FOR OUTDOOR TEMPERATURE SENSOR
The location of the Outdoor
Temperature Sensor
FIGURE 3 – OUTDOOR TEMPERATURE SENSOR LOCATION
must meet the following
requirements (see FIGURE 3):
1. Must be mounted out
of direct sunlight on the
North, East or West side
of the house.
2. Must be at least 3 feet
from all exhaust vents.
OUTDOOR
3. Must be above the

SENSOR LEADS
expected snow line.
A convenient way to route the sensor wire outside is to make used of unused wires running to
the A/C condensing unit (if applicable). Other ways are to use existing holes for Cable TV lines,
telephone lines, AC line, etc.
ELECTRICAL INTERFERENCE CAN CAUSE OUTDOOR TEMPERATURE SENSOR INACCURACY.
• Do not run Outdoor Temperature Sensor alongside wires carrying high voltage
(120VAC or higher).
• Do not run Outdoor Temperature Sensor wire lengths greater than 100 feet.
Run wire from the humidistat to the Outdoor Temperature Sensor. Secure the sensor bracket with
a #8 screw.
