NOTE:

Polarity is important and must be observed. It is also vital that the 24 VAC common side of the transformer be Earth

grounded.

Step 2:

Hook up applicable BACnet, and/or local Building Automation System (BAS) according to wiring diagram. Multiple

units can be daisy chained together using optional RJ45 cables. If using BAS or Local Set point, reference the airflow

setpoint section on the next page.
