Economizer Damper Actuator

The Economizer Damper Actuator signal voltage output is a 2-10 VDC

output. This signal output is used by the VCM-X E-BUS Controller

to modulate the Economizer Damper Actuator in order to control the

amount of Outdoor Air delivered to the HVAC unit for Free Cooling and/

or Indoor Air Quality requirements. See Figure 13 for detailed wiring.

Warning: It is very important to be certain that all wiring is

correct as shown in the wiring diagram below. Failure to observe

the correct polarity will result in damage to the actuator or VCM-X

E-BUS Controller.
