A shutdown procedure activates when a low temperature alarm input is closed. The procedure varies depending on the following two situations:

  • When triggered and proportional heating or cooling is defined, the dampers fully close and the cooling or heating output is set to the failsafe position, and the fan stops.
  • When triggered and no proportional heating or cooling is defined, the dampers fully close and the unit remains operating.
