Further settings depend on the inlet tank valve used.
BoosterControl Advanced can control the following valves:
▪ Motorised gate valve (ð Section 8.5.3.6, Page 49)
▪ Proportional valve (ð Section 8.5.3.1, Page 47)
8.5.3.6 Level control via motorised gate valve
If a motorised gate valve is used.
Log in to BoosterControl Advanced at service or factory access level.

8.5.4 Parameterising the accumulator function (frequency-controlled systems only)

Before the system stops, an accumulator can be pressurised up to a certain limit
value. As the last pump is running, a check is periodically carried out while gradually
reducing pump output to determine if the switch-off point was reached. When this
switch-off point is reached, an accumulator can be charged to an increased pressure
before the system is stopped.
Subsequently tapped small quantities of water are then supplied from the
accumulator first before the system starts up again (energy-saving mode).
Log in to BoosterControl Advanced at service or factory access level.

8.5.5 Water flow detection (WSD)

The water flow detection function can be implemented by means of an accumulator
installed on the discharge side. If used, the set-up is as follows:
▪ Connect the water flow detector to inputs WSD1 to WSD3 (DI 1 - 3) as required.
▪ Connect the temperature sensor (PT1000) to terminal J401.
