The pump restarting pressure is linked not only to the set pressure SP but also to RP. RP expresses the decrease in
pressure, with respect to "SP" caused by the pump starting.
For example: SP = 3,0 [bar]; RP = 0,5 [bar]; no active auxiliary setpoint function: During normal operation the system is pressurised at 3,0 [bar].
The electropump restarts when the pressure falls below 2,7 [bar].
Setting a pressure (SP, P1, P2, P3, P4) that is too high for the pump performance may cause false water lack errors
BL; in these cases lower the set pressure.
13.2.4. Manual Menu
In manual operation, the sum of the input pressure and the maximum pressure that can be supplied must not be greater
than 6 bar.
