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.
