CAV corresponds to a single on/off clock that, for example, switches the unit on at 07:00 and off again at 17:00.

The clock and weekly schedule control on/off of the ventilation unit.

Any clock can be overridden via a switch or motion sensor.

CAV – constant airflow

CAV – constant ventilation

We recommend CAV when:

  • There is a uniform need for ventilation
  • There is a low fluctuation in the person load
  • There is a low fluctuation in the heat load

 

Examples of this are:

Copy rooms, corridors and toilets
