8 Solar pump
8.1 Operating data
The pump UPM3 Solar is a high-efficiency pump designed to function with
and without the PWM signal, therefore enabling the following curves:
3 Constant curves (functioning without PWM signal)
One PWM curve with solar profile C (stopping without PWM signal)
Importante
The pump is preset to curve with profile C PWM by default.
Importante
If the controller does not have an PWM output, do not connect the
signal cable and program the pump with constant curves.
The UPM3 Solar operation panel is designed with a single button, one red/
green LED and four yellow LEDs.

If multiple alarms are active at the same time, the LEDs will only display
the highest priority error. The priority is defined by the sequence in the
