AirModule
Heat pump AirX connected to heat pump module AirModule provides a
complete installation for both heating and domestic hot water, since the
heat pump module contains a hot water cylinder. Switching between
heating and DHW is managed by an internal 3-way valve. The integrated
booster in the heat pump module will turn on if needed.

Airbox E
When heat pump AirX is connected to heat pump module AirBox E, an
external hot water cylinder is required if the purpose of the heat pump is
also to produce hot water. In this case, switching between heating and
DHW is managed by an external 3-way valve. The integrated booster in
the heat pump module will turn on if needed.

Airbox S
When heat pump AirX is connected to heat pump module AirBox S, an
external hot water cylinder is required if the purpose of the heat pump is
also to produce hot water. In this case, switching between heating and
DHW is managed by an external 3-way valve. The module contains a
mixing valve that regulates the heat from the external booster, which is
turned on when needed.
