3.1. UPM3 FLEX AS 25-75 130 PUMP
UPM3 FLEX AS 25-75 130 pump is a wet running circulator. Its speed can be controlled either
by selecting a pump performance curve or by a PWM signal.

Pump control
The circulation pump can be controlled by an external PWM signal (profile for use in heating
systems) or without a PWM signal by selecting a pump performance curve.
A maximum curve of a pump working range can be defined:
- with PWM signal the pump speed changes with the signal value up to the maximum
of the selected curve
- without PWM signal the pump runs at the max. speed according to the selected curve
