INSTALLATION AND WIRING

Supply Fan VFD Signal or Zoning

Bypass Damper Actuator Signal

The Supply Fan VFD or Zoning Bypass Damper Actuator Signal is a
0-10 VDC output. This signal output can be connected to the Supply
Fan Variable Frequency Drive to modulate the Supply Fan speed and
control Duct Static Pressure utilizing the Duct Static Pressure Sensor
connected to the RNE Controller. Alternatively, it can be connected to a
Zoning Bypass Damper Actuator that will modulate the Zoning Bypass
Damper Actuator to control Duct Static Pressure utilizing the Duct Static
Pressure Sensor connected to the RNE Controller. A Duct Static Pressure
Sensor must be connected in order for the VFD or Zoning Bypass Damper
Actuator to operate. See Figures 15 and 16 below for detailed wiring.

CAUTION: Variable Frequency Drive units can cause large
transient noise spikes which can cause interference to be propagated
on other electronic equipment. Use shielded wire wherever possible
and route all sensor and controller wiring away from the Variable
Frequency Drive and the HVAC Unit electrical wiring.

Caution:

The VFD Unit Must Be Configured For 0-10 VDC Input.
The Input Resistance At The VFD Must Not Be Less
Than 1000 Ohms When Measured At The VFD
Terminals With All Input Wires Removed.
