VCM-X Modular E-BUS Controller Technical Guide 20
The VCM-X Expansion Module must be connected to 24 VAC as shown
in the wiring diagram below. Please see Table 1 on page 10 for correct
VA requirements to use when sizing the transformer(s) used for power-
ing the expansion module.
Also please note that when wiring the VCM-X Expansion Module, its
contacts must be wired as wet contacts (connected to 24 VAC).

WARNING!!
Observe Polarity! All boards must be wired with GND-to-GND and
24VAC-to-24VAC. Failure to observe polarity will result in damage to
one or more of the boards. Expansion Modules must be wired in
such a way that the expansion modules and the controller are
always powered together. Loss of power to the expansion module
will cause the controller to become inoperative until power is
restored to the expansion module.

Note:
1.) The Modulating
Cooling Device Used
Must Be Capable Of
Accepting Either A 0-10
VDC, 2-10 VDC or 1.5-
5.0 VDC Input. The
Modulating Cooling
Output Voltage Is User
Configurable For These
Voltages. The
Modulating Heating
Devices Used Must Be
Capable of Accepting
Either A 0-10 VDC or 2-
10 VDC Input. The
Modulating Heating
Output Voltage Is User-
Configurable For These
Voltages. These Voltage
Outputs Must Also Be
Configured When You
Are Setting Up The
VCM-X Controller(s)
Operating Parameters.
2.) Each Modulating
Heating Or Cooling
Device Used On The
VCM-X Controller Must
Have (1) Relay Output
Configured For Each
Device Used, In Order
To Enable The
Modulating Heating
And/Or Cooling Device's
Sequence. This Relay
Output Must Be
Configured When
Setting Up The VCM-X
Controller Operating
Parameters.
Relay Output Contacts R1 Through R4 May
Be User-Configured For The Following:
Note:
-
1 - Heating Stages
2 - Cooling Stages
3 - Warm-up Mode Command (VAV Boxes)
4 - Reversing Valve (Heat Pumps)
5 - Reheat Control (Dehumidification)
6 - Exhaust Fan Interlock
7 - Preheater For Low Ambient Protection
8 - Alarm
9 - Override
10 - Occupied
11 - OA Damper
12 - Heat Wheel
13 - Emergency Heat
A Total Of 20 Relays Are Available By
Adding Relay Expansion Modules. All
Expansion Module Relay Outputs Are User
Configurable As Listed Above.
Note:
All Relay Outputs Are Normally
