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 Boards must be wired in such a way that power to
both the expansion boards and the controller are always powered together.
Loss of power to the expansion board will cause the controller to become
inoperative until power is restored to the expansion board.

The Cooling Device Used Can Be A
Modulating Chilled Water Valve or A Digital
Scroll Compressor. If Using A Digital Scroll
Compressor Please See Digital Scroll
Detailed Wiring Information In This Manual.
The Heating Device Used Can Be A
Modulating Hot Water Valve, Modulating
Steam Valve or SCR Controlled Electric
Heating Coil.
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 AOUT1
Output Voltage Is User Configurable For These Voltages.
The AOUT2 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.
These
Voltage Outputs Must Be Configured When You are Setting-up The
VCM Controller(s) Operating Parameters. See the VCM Controller
Operator Interfaces Technical Guide For Complete Controller
Programming and Configuration Information.
2.) Each Modulating Heating Or Cooling Device Used On The VCM
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 Controller Operating Parameters. See the VCM
Controller Operator Interfaces Technical Guide For Complete
Controller Programming and Configuration Information.
