Caution:
If your HVAC unit is supplied with the MODGAS II controller with or without an MHGRV II controller,
the Supply Air Temperature Sensor must always be wired to the MODGAS II controller. If your HVAC
unit is supplied with only the MHGRV II controller, the Supply Air Temperature Sensor must be
connected to the MHGRV II controller. If you have either of these controllers on your HVAC unit and
have a Supply Air Temperature Sensor connected to the VCM controller, your controls will not function
correctly. Only one Supply Air Temperature Sensor can be used on an HVAC unit. If expansion boards
are used they can be connected via modular cable to any IC2 connector on the loop.
