Together with the W5 ventilation unit, you
can use a separate water heated air heater
which is installed in a duct. The air heater is
commissioned and set using a Smart control
panel. Commissioning and setting are

exchanger is a built-in function in the ventila-
tion unit. This function is used to prevent heat
recovery when it is hot during the summer.
