Supply Fan VFD Signal or Bypass
Damper Actuator
The Supply Fan VFD Signal is a user-adjustable signal with a
range of 0-10 VDC from AO1 on the VCCX2 Controller. This
signal output can be connected to either:
• The Supply Fan VFD to modulate the supply fan speed.
• A bypass damper for zoning applications.
See Figure 20, this page for detailed wiring.
CAUTION: VFD 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
VFD and the HVAC unit electrical wiring.
