Application limits for the heat pump: Heating (heat source = groundwater)
– At the same volume flow rates in the heating circuit (ΔT 5 K or ΔT 8 K) and the groundwater circuit (ΔT 3 K) as for the
nominal heat output test under standard nominal conditions. Operation of the pump outside the application limits results
in the heat pump being switched off by the internal control and safety devices.
