Application limits for the heat pump: Heating (heat source = brine)
– At the same volume flow rates in the heating circuit (ΔT 5 K or ΔT 8 K) and the brine 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.
– Application limits for the heat pump: Heating:
– B-10/W20
– B-10/W55
– B−3/W60
– B20/W60
– B20/W20
– To be able to achieve the B−10/W20 and B−10/W55 operating limits, you must change the freeze protection in the
configuration from the factory setting to -13 °C.
