Dual pump management

Installation and operating instructions • Wilo-Yonos GIGA2.0-I/-D • Ed.01/2023-03
It is possible to switch off the pump via the manual function "Pump On/Off". The motor is
stopped and the control mode with the set control function is interrupted.
In order for the pump to continue running in the set control mode, it must be actively
switched on again via "Pump On".
DANGER
Risk of fatal electrical shock!
The "Pump OFF" connection only overrides the set control function and
only stops the motor. This means that the pumps are not voltage-free.
• Always disconnect the pump from the power supply for maintenance
work!
The electronic module is equipped with a non-fading memory for saving the configuration.
If the mains supply is interrupted for any length of time, all settings and data are retained.
When power is restored, the pump continues to run with the default values that were
present before the interruption.
All Yonos GIGA2.0 pumps are equipped with integrated dual pump management.
A twin-head pump connection can be established or disconnected in the "Dual pump man-
agement" menu. The twin-head pump function can also be set here.
The dual pump management has the following functions:
• Main/standby operation:
Each of the two pumps provides the configured flow rate. The other pump is available in
case of malfunction or runs after pump cycling.
Only one pump runs at a time (factory setting).
The main/standby operation is also completely active even for two similar single pumps
in a twin-head pump installation in the Y-piece.
• Efficiency-optimised peak-load operation (parallel operation):
In peak-load operation (parallel operation), the hydraulic output is provided jointly by
both pumps.
In the partial load range, the hydraulic output is initially provided by just one of the two
pumps.
If the sum of the electrical power consumption P1 of both pumps in the partial load
range is less than the power consumption P1 of one pump, then the second pump is
switched on with optimised efficiency.
This operating mode optimises operational efficiency compared to conventional peak-
load operation (exclusively load-sensitive switching on and off).
If only one pump is available, the remaining pump takes over the supply. The possible
peak load is limited due to the power of the single pump. Parallel operation is also pos-
sible with two single pumps of the same type in twin-head pump operation in the Y-
piece.
• Pump cycling:
The actively operated pump is regularly changed automatically to guarantee even usage
of both pumps in the event of single pump operation. If only one pump (main/standby,
peak load or night setback) is running, the pump being operated is changed after a run-
ning time of 24 h at the latest. Both pumps run at the time of pump changeover so that
operation is not interrupted. The operated pump can be replaced at least every 1 hour
and can be set in length increments up to a maximum of 36 hours.
NOTICE
Even after switching the mains voltage off and on again, the remaining
time until the next pump cycling continues to run. The timer does not
start again from the beginning!
