Mechanical ventilation
For mechanical ventilation, a Viessmann ventilation
unit is connected to the heat pump control unit via
Modbus. This enables full operation of the mechanical
ventilation system and setting of the control parame-
ters via the heat pump control unit. Changed parame-
ters are transferred to the ventilation controller integra-
ted in the ventilation unit. Commissioning (e.g. function
check) and diagnosis (e.g. system overview, scanning
messages) can also be undertaken at the heat pump
control unit.
