4.2 General Description
The Living HP is extract air ventilation unit with integrated heat pump section to recover heat from extract
air and deliver heat to building heating system. The Living HP unit should be integrated in building extract
air ventilation system and is designed to control fire/smoke fan during normal operation.
The stops and starts of the unit are based on the ambient air temperature. The default value set to
start the unit is +15°C. This value can be changed in the control panel. Other conditions which should
be met for the heat recovery to start:
• water flow should be more than 0,5 m³/h
• extract air temperature should be more than +10°C
• air pressure drop should be more than 30 Pa
These values can also be changed in the control menu.
