6.3 Function of the unit (Fig. 1)
All components of the unit are mounted on a base
frame (Item 1).
The main component in the unit is a self-priming,
horizontally mounted, multistage centrifugal
pump (Item 2). The centrifugal pump (Item 2)
draws in rainwater from a rainwater collector tank
and pumps it to the points of consumption.
A pressure sensor (Item 7) determines the pres-
sure drop in the pressure pipe when water is drawn
at the points of consumption. As soon as a defined
start-up pressure is reached, the centrifugal pump
switches on automatically and pumps water to
meet the demand.
Control, monitoring, recording, setting and display
of all operating processes is performed by a
switchgear device (Item 3) with a microcontroller
unit (CPU). Operation of the unit and setting of its
parameters are performed via menus using the
function keys and display on the switchgear
(Item 3).
The water level in the collector tank is determined
by a level sensor (Item 11).
If there is insufficient rainwater, the unit can
switch over automatically to supply potable water
to the consumer network from a potable water
replenishment reservoir (Item 4). A solenoid valve
(Item 9) is used for the switchover.
Other functions:
• Water exchange in potable water replenishment
reservoir controlled according to pump operating
time
• Prevention of lime deposits by automatic actua-
tion of the solenoid valve
• Integrated automatic switch-off in the event of
dry running
• Permanent operating data recording, economy
mode function and operating status log
6.4 Operating modes
• Automatic: Automatic switchover between rain-
water and potable water supply, depending on the
water level in the collector tank.
• Off: The pump and the solenoid valve are not acti-
vated by the switchgear. The switchgear remains
functioning.
• Manual: This operating mode is available for after-
sales service technicians to check the functioning
of the pump and the solenoid valve.
• Potable water: Continuous supply from the pot-
able water replenishment reservoir regardless of
the water level in the collector tank.
