If DAT Limiting is enabled, and a DAT sensor is not connected, the controller
will lockout reheat control only in the cooling mode. The unit will operate
this way until a DAT sensor is detected or until the unit is commanded to
control to the Active Heating Setpoint by a supervisory BMS.
If the unit has detected a DAT sensor and DAT Limiting is not enabled, the
unit’s reheat is controlled by the Heating loop instead of the DAT loop.
