UPM3 FLEX AS and UPM3 DHW
This pump is either externally controlled with a PWM A profile signal
control or speed selection.
The maximum curve of the pump operating range can be defined.
• With PWM signal, the pump runs at the corresponding speed.
• Without PWM signal, the pump runs at maximum speed.

7.4.5 UPMO
This pump is internally controlled with control mode CC or
externally with PWM signal control with profile A.
The pump automatically enables the PWM input-signal control
mode by SignalDetect when the signal cable is plugged in.

If the pump does not detect a PWM signal or if the signal equals 0,
the pump returns to its previous control mode.

Proportional pressure
The head (pressure) is reduced at falling heat demand and
increased at rising heat demand.
The duty point of the pump moves up or down on the selected
proportional-pressure curve depending on the heat demand in the
system.
TM060704
• PP1: lowest proportional-pressure curve
• PP2: intermediate proportional-pressure curve
• PP3: highest proportional-pressure curve
• AUTO
ADAPT
: highest to lowest proportional pressure curve.
