Caution
If possible, use the pump modulation signal. This provides the
most accurate pump control.
In positions 3 to 9 the control PCB receives no signal from the
boiler and the boiler responds as in position 0.
If the automatic burner unit does not support pump modulation,
the pump will behave as an on/off pump.
Select the type of signal that controls the pump using the rotary knob SW2
on the PCB. See table below.
