If an external controller is installed, the pump is able to change from one constant curve to
another, depending on the external signal.
You can also set the pump to operate according to the maximum or minimum curve, like an
uncontrolled pump:
• You can use the maximum curve mode in periods in which a maximum flow is required.
This operating mode is for instance suitable for hot-water priority.
• You can use the minimum curve mode in periods in which a minimum flow is required.
This operating mode is for instance suitable for manual night setback if you do not want
automatic night setback.
Constant curve
In systems requiring a constant flow, independently of pressure drop.
Examples
• chillers for air-conditioning
• heating surfaces
• cooling surfaces.
Constant flow rate
In systems requiring a constant tank level, independently of the flow rate.
Examples
• process water tanks
• boiler condensate tanks.
Constant level
In systems with pumps connected in parallel.
The multipump function enables the control of two to four 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 or the
wired GENI connection.
