Economizer Damper Actuator
The Economizer Damper Actuator signal voltage output is a 2-10 VDC
output. This signal output is used by the RNE 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 14 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 RNE
Controller.
