Wall Sensor
Locate the sensor on a wall where exposure to unrestrict-
ed air circulation represents the average temperature of
the space. A common mistake is to mount the sensor too
close to the supply air diffuser in a room. This causes short
cycling of the air conditioning unit and large room tempera-
ture swings.
Note:
All sensors have black (common), white (thermistor), and
red (LED) wires. With the tenant override and /or set point
adjustment option, a green wire is provided. The optional
thermometer does not affect wiring.
Refer to IM 529 for detailed installation instructions.
