Application limits for the heat pump: Heating (heat source = brine)
–
At the same volume flow rates in the heating circuit (
Δ
T 5 K or
Δ
T 8 K) and the brine circuit (
Δ
T 3 K). Operation of the
pump outside the application limits results in the heat pump being switched off by the internal control and safety devices.
