Application limits for the heat pump: Heating and cooling (heat source = air)
At the same volume flow rates in the heating circuit (
Δ
T 5K or
Δ
T 8 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.
