6.12. AERO ILM HGL with cooling and HGL usage in one step
When the heat pump works in cooling mode, the
waste heat is used for hot water supply. For this, the
hydraulic needs to be extended with a HGL return
and the associated pump (accessory).
To switch the operation of the heat pump from heat-
ing to cooling a cooling valve has to be installed in the
heat pump inlet and heat pump outlet.
It is additionally necessary to install a cooling valve in
the heating circuit supply.
