The pump group is a premounted group of fittings for the return temperature maintenance of
the boiler. The actuator of the mixing valve is equipped with a constant temperature controller.
The pump can be isolated by means of the ball valves and the mixing valve.
The pump can thus be maintained easily without draining the heating circuit system. The pump
group is mounted directly on a wall bracket.
The pump group and its insulation comply with EnEV.
