Description
Sub-menu with values for setting the set-
point
Nominal pressure for switching on the
main pump (MP)
Nominal pressure for switching off the
main pump (MP) depends on the charac-
teristic curve selected in menu 5.04; set-
point must be at least 0.5 bar above the
start-up pressure
Delay in switching off a pump when the
switch-off value is reached and the cur-
rent value is still above this
Starting time relative to the start-up of
the main pump (MP)
Switch-off time relative to the start-up of
the main pump (MP)
Switch-off pressure difference between
TWM (drinking water mode) and RWM
(rainwater mode)
To protect the pump during operation and
when the pump no longer reaches the
switch-off pressure, a time can be set in
menu 1.26 after which the switch-off
pressure is reduced.
Defines the time after which the switch-
off pressure is reduced by the value set in
menu 1.27.
