Multipump function

The multipump function enables the control of single-head pumps

connected in parallel and twin-head pumps without the use of

external controllers. The pumps in a multipump system

communicate with each other via the wireless GENIair

connection.

Pump system:

• Twin-head pump.

• Two single-head pumps connected in parallel. The pumps

must be of the same type and size. Each pump requires a

non-return valve in series with the pump.

You can set a multipump system from a selected pump, which will

then be the master pump.

Check the display to identify the master pump in a multipump

"Alternating operation"

Fig. 53 "Alternating operation"

Alternating operation functions as a duty-standby operating mode

and is possible with two pumps of same size and type connected

in parallel. The main purpose of the function is to ensure an even

amount of running hours and to ensure that the standby pump

takes over if the running pump stops due to an alarm.

"Back-up operation"

Fig. 54 "Back-up operation"

Backup operation is possible with two pumps of same size and

type connected in parallel. Each pump requires a non-return

valve in series with the pump.

One pump is running continuously. The backup pump is operated

for a short time each day to prevent seizing up. If the duty pump

stops due to a fault, the backup pump starts automatically.
