Fig. 7-9: p/Q parameter group selection
If the two points / double pump function is active (see F4.03 bit3), the p/Q pa-
rameter selection function shown in the figure above will be deactivated, and
the p/Q controller parameter sets can only be switched according to the pump
switching logic.

Tab. 7-9: Parameter list of p/Q PID controller proportional gain setting
The parameter F3.12 is used to set the proportional gain of p/Q PID controller.
Pressure loop response is faster with a higher proportional gain. But excessively
high proportional gain can cause pressure over modulation and pressure oscilla-
tion.
