Aquarea air-to-water heat pumps - Planning and installation manual - 02/2022
Product Description
4
The ventilation unit provides fresh filtered outside air to a residential building while keeping a high
thermal comfort within the building by using the exhaust indoor air to precondition the incoming air,
leading to lower heating requirements in the building. To this end, the unit is equipped with a highly
energy-efficient rotary heat exchanger with EC technology fans.
For a space-saving solution, the compact ventilation unit is optimised for installation atop the
Panasonic Square Tank (PAW-TA20C1E5C) or the Aquarea All in One Compact indoor units (WH-
ADC0309J3E5C, WH-ADC1216H6E5C). However, it can also be combined with Aquarea mono-
bloc or bi-bloc systems. In all these cases, the residential ventilation unit and the Aquarea heat
pump can be controlled with one single user-friendly controller.
The residential ventilation unit is available in two versions: with the supply air connection on the
left-hand side (PAW-A2W-VENTA-L) or on the right-hand side (PAW-A2W-VENTA-R).
