Anyone have experience doing VAV supply air cooling setpoint on the RTRM board using an analog DCV? The literature also says that this can be accomplished on the RTAM board.. What will yield the best results and reliablity? I am thinking also that SA reset might be more reliable way to go with 0 DCV for zero reset and 2.4 DCV for 20 Deg F. These low DCV values are sort of troublesome. This unit is a VAV unit with a VSD.. There is not LON available on site and we are using a radio comm link with a controller.
