2.3.3. Circulation Pump
MINERWA is equipped with a pump having controlled by
an external signal PWM (i=feedback signal), the main PCB
of combi boiler sends a PWM signal as an actuating variable
to the pump. It should be controlled that the pump ensures
required flow rate depending on the critic line pressure loss
(see figure 21 and 22)..
