SENSOR INSTALLATION AND WIRING
2.5
Two types of sensors may be installed, including a Header Sensor and an Outside Air Sensor.
The Header Sensor is required for all modes of operation. The Outdoor Air Sensor is required
for operation in the Outdoor Reset Mode. All Sensor wiring should be run separately from power
wiring to avoid inducing electrical noise on the sensor wiring.
If desired, an optional Return Sensor may also be installed, which is the same type and part
number as the Header Sensor, however it is only used for Plant DT limit operation and for
monitoring purposes.
