Table 5: User-Confi gurable Relay Outputs
No. Relay Description Details
1
Cooling Stage
Confi gured for each fi xed stage of cooling (except heat pump compressor).
2
Heating Stage
Confi gured for each fi xed stage of heating.
3
Aux Heat
Confi gured for a fi xed stage of Aux Heat in a heat pump unit.
4
Emergency Heat
Confi gured for a fi xed stage Emergency Heat in a heat pump unit.
5
Mod Heat Enable
Confi gure if a 0-10 VDC Modulating Heat source needs a relay to enable it.
6
Mod Cool Enable
Confi gure if a 0-10 VDC Modulating Cool source needs a relay to enable it.
7
Morning Warm-Up/
Cool-Down (VAV Boxes)

10
Low Ambient
Confi gure for Low Ambient operation.
11
Exhaust Fan
Confi gure (1) Relay for enabling exhaust fan when Building Pressure Control is used.
12
Economizer Active
If confi gured, this relay will energize if unit is in Economizer mode and the damper has moved 5%
above its Economizer Minimum Setpoint position.
13
Heat Wheel
Confi gure (1) Relay that turns heat wheel on when in occupied operation and turns heat wheel off
when in Economizer Mode.
14
Occupied Active
If confi gured, this relay will energize whenever the unit is in the Occupied Mode.
15
Override Active
If confi gured, this relay will energize anytime the space sensor Push-button override is active.
16
Alarm Active
If confi gured, this relay will energize anytime a VCC-X alarm is active.
VCC-X EM1 Expansion Module Inputs & Outputs
AOUT3 - Return Air Bypass Damper Actuator
Signal
This output signal is a Direct Acting 0-10 VDC output signal that is
used to modulate a Return Air Bypass Damper Actuator in concert
with a Return Air Damper Actuator for AAON
®
PAC or DPAC
control schemes.
R1-R5 - User-Confi gurable Relays
These relays are confi gurable by the user. For all the available
confi guration options, see Table 5.
E-BUS 12-Relay Expansion Module
Please refer to the user-confi gurable relays in Table 5 for relay
defi nitions.
VCC-X EM1 Expansion Module
T3 - Economizer Feedback
If Title 24 Economizer operation has been confi gured, this input will
be used for the 0-10 VDC Feedback Signal from the Economizer
actuator.
AOUT1 - Modulating Chilled Water
Valve Actuator
This output is used to control a Modulating Chilled Water Valve
Actuator to maintain the Cooling Supply Air Temperature Setpoint.
This output can be confi gured with a user-adjustable voltage range
of operation which can be set up to provide either direct or reverse
acting operation.
AOUT2 - Return Air Damper Actuator Signal
This output signal is a Direct Acting 0-10 VDC output signal that
is used to modulate a Return Air Damper Actuator in concert with
a Return Air Bypass Damper Actuator for AAON
®
PAC or DPAC
control schemes.
