Optional accessories

● Regulating valve

● Actuator for the regulating valve

● Water temperature regulation (feature)

2.6.8 Speed control for heating circuit pumps

UPM3 auto ver. 1

Each heating circuit requires its own Grundfos UPM3 AUTO circulation pump. The

pump has three operating modes: Proportional pressure control, Constant pressure

control and Constant curve control. By default, the pump operates in proportional

pressure mode 3.

If a radiator system is used and a high flow rate causes noise in the pipes, you can

reduce the noise by using constant pressure mode 1 or 2.

Check the pump’s current operating mode by pressing the pump’s button briefly.
