Performance data
The following performance data is applicable to new products with clean heat exchangers.
Check conditions for determining the performance data in accordance with EN 14511
Installation: Connection pipes on the heat source side between VWF xx/4 and VWW xx/4 SI = 2 x 2 m (pipe internal diameter
= 32 mm), environment circuit pump setting: Heating mode: Factory setting (auto), Cooling mode: Factory setting (auto)

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