13.6 Assisted fault advice
This submenu provides information about faults and corrective
actions.
13.7 Wireless GENIair
The pump is designed for multi-pump connection via the wireless
GENIair connection or wired via a bus system
(Building Management System).
The built-in wireless GENIair module enables communication
between pumps and with the Grundfos Go Remote without the
use of add-on modules:
•
Multi-pump function.
See section 13.8 Multi-pump function.
•
Grundfos GO Remote.
See section 17.1 Grundfos GO Remote.
13.8 Multi-pump function
The multi-pump 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 multi-pump system
or
and press
communicate with each other via the wireless GENIair
connection.
A multi-pump system is set up via a selected pump, i.e. the
master pump (first selected pump). All Grundfos pumps with a
wireless GENIair connection can be connected to the multi-pump
system.
The multi-pump functions are described in the following sections.
13.8.1 Alternating operation
Only one pump is operating at a time. The change from one pump
to the other depends on time or energy. If a pump fails, the other
pump will take over automatically.
Pump system:
•
Twin-head pump.
•
Two single-head pumps connected in parallel. The pumps
must be of same type and size. Each pump requires a
non-return valve in series with the pump.
13.8.2 Back-up operation
One pump is operating continuously. The back-up pump is
.
operated at intervals to prevent seizing up. If the duty pump stops
due to a fault, the back-up pump will start automatically.
Pump system:
•
Twin-head pump.
•
Two single-head pumps connected in parallel. The pumps
must be of same type and size. Each pump requires a
non-return valve in series with the pump.
13.8.3 Cascade operation
Cascade operation ensures that the pump performance is
automatically adapted to the consumption by switching pumps on
or off. The system thus runs as energy-efficiently as possible with
a constant pressure and a limited number of pumps.
All pumps in operation will run at equal speed. Pump changeover
is automatic and depends on energy, operating hours and fault.
Pump system:
•
Twin-head pump.
•
Two single-head pumps connected in parallel. The pumps
must be of same type and size. Each pump requires a
non-return valve in series with the pump.
The control mode must be set to "Const. press." or "Constant
•
curve".
