8301-067 Outdoor Temperature/Humidity Sensor

8301-067 Sensor Connections

This unit utilizes a two wire 4-10mA signal from
the 8301-067 sensor to communicate outdoor
humidity and a 10KΩ Type III (AN) thermocouple
from the 8301-067 sensor to communicate outdoor
temperature. The humidity sensor is connected to
the sensor control board via the J13 connector. The
thermocouple wires are loose in the sensor housing and
require a butt splice connector or wire nut to connect to
the main unit wiring harness. See Figure 61 and Figure
62 for sensor wiring and terminal location.
