Up to two additional temperature/humidity sensors may be added.
Be sure the sensors are connected to the proper
terminals on the terminal block and sensor as listed below.
See page 22 for information on correct sensor jumper
position.
FIGURE 20
Additional Remote Temperature and Temperature/Humidity Sensor Installation
Up to two additional temperature and humidity sensors can be purchased and installed. Alternately, temperature-
only sensors can be purchased and installed instead of the combination sensors. Use shielded cable to connect
additional sensors to controller.

Temperature-only sensors can be used in place of the additional temperature/humidity sensors. #2 temperature-only sensor
will connect to TB# 26 and 27. #3 temperature-only sensor will connect to TB# 28 and 29. The wire connections for the
temperature-only sensors are not polarity sensitive.
