85 % Minimum modulation value in heating mode
100% Maximum value in heating mode
To prevent flow noise, you must pay attention to the hydraulic design of
the heating installation.
The system uses a high-head, modulating pump that is suitable for use on
any type of one- or two-pipe heating system. The automatic air vent valve
built into the pump body enables fast venting of the heating system.
Operation of the pump in DHW mode —> 100% fixed.
Operation of the pump in heating mode —> modulating by 85% to 100% .
