F135 is an accessory that makes it possible to combine an air/water heat pump with mechanical exhaust air. The heat in the building’s ventilation air is utilised by F135 and used to heat the building and the hot water at the same time as ventilating the building. F135 is connected between the indoor module and the air/water heat pump, and all control of F135 takes place from the indoor module.
