Applications
The energy-efficient circulation pump is designed for water circulation in heating systems.
Underfloor heating systems
Single-pipe systems
Two-pipe systems
Pumping liquid:
Clean, non-aggressive and non-explosive liquids, not containing solid particles, fibers or mineral/vegetable oil
In heating systems, water must meet the requirements of accepted standards of water quality in heating systems.

Operating modes
Automatic mode (factory setting):
In this mode the pump automatically sets the operating pressure, depending on the hydraulic system. This mode is recommended in most systems.
Proportional pressure mode:
The circulator changes the pressure proportionally to the current flow.
The pressure value can be adjusted on three curves.
Constant pressure mode:
The circulator maintains the pressure constant when the reference flow changes.
The pressure value can be adjusted on three curves.
Fixed speed mode:
The circulator works with constant curve and the curve could be changed over three curves.
Night mode:
The pump is changed to an automatic deceleration curve at night, so that it runs at low performance and low energy consumption.
The circulator can operate in:
- automatic mode
- proportional pressure mode
- constant pressure mode
- fixed speed mode
- night mode.
