Indoor Wall-Mounted Humidity Sensor
When used, the OE265-11 Indoor Wall-Mounted Humidity Sensor is
connected to the system by wiring it to the AI2 input on the SA Expan-
sion Module. It must be wired as shown in Figure 21 below for proper
controller operation.
Warning: It is very important to be certain that all wiring is
correct as shown in the wiring diagram below. Failure to observe
the correct polarity will result in damage to the Space Humidity
Sensor or SA Expansion Module.

WARNING!!
Observe Polarity! All boards must be wired with GND-to-GND and
24VAC-to-24VAC. Failure to observe polarity will result in damage to
one or more of the boards. Expansion Module must be wired in such a
way that the expansion module and the controller are always powered
together. Loss of power to the expansion module will cause the
controller to become inoperative until power is restored to the
expansion module.
