With temporisation activated, the pumps can reach their maximum pressure.
Check that this pressure is not harmful to the system, the distribution system or
the devices.
Taking off clips ET1 and ET2, you exclude minimum timing (initial
3'') and working timing and, in case of contemporary closing of the
manostats, the pumps will start contemporarily.
The SLC potentiometer allows adjusting the sensitivity of the
electric probes in case 3 electrodes are used for level control in the
first gathering tank.
