Wiring For MODGAS II When Used With Orion VCM-X E-BUS Controller
Note:
1.) When The MODGAS II Controller Is Used With The VCM-X
Controller It Must Have (1) Relay Output On The VCM-X Controller
Configured For The MODGAS II Controller In Order To Function
Correctly. This Relay Output Must Be Configured When Setting-up
The Controller(s) Operating Parameters. See the VCM-X Controller
Operator Interfaces Technical Guide For Complete Controller
Programming and Configuration Information.
Caution:
The Supply Air Temperature Sensor Always Connects To The VCM-X Controller And The
Supply Air Temperature Is Broadcast To The MODGAS II Controller, MHGRVII And The
MHGRVIII Controller From It.
