8. UPM3 HYBRID 25-70 Pump

Pump control

The circulation pump can be controlled:

• internally without PWM signal by selecting a proper mode and pump curve.

• externally by PWM C control signal (profile for solar systems)

WARNING – IMPORTANT

The pump permits to be controlled also by PWM A signal (profile for use in heating systems).

This mode must not be used for solar thermal systems.

Using the PWM A pump profile would cause system damage.
