module.
This menu guides you through the following:
• Select date format. See section 13.28 "Date and

13.45 "Multi-pump setup" (Setup of
multi-pump system)
The multipump function enables the control of two
pumps connected in parallel without the use of
external controllers. The pumps in a multipump
system communicate with each other via the
wireless GENIair connection or the wired GENI
connection.
You can set a multipump system via the master
pump, i.e. the first selected pump.
If two pumps in the system are configured with an
outlet-pressure sensor, they can all function as
master pumps and take over the master pump
function if the other should fail. This provides
additional redundancy in the multipump system.
The multipump functions are described in the
following sections.
13.45.1 "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 starts if the duty pump stops due to an alarm.
Each pump requires a non-return valve in series with
the pump.
You can choose between two alternating operation
modes:
• "Alternating operation, time"
Change from one pump to the other is based on
time.
• "Alternating operation, energy"
Change from one pump to the other is based on
energy consumption.
If the duty pump fails, the other pump starts.
