In heating systems with a fixed system characteristic, for example domestic hot-water systems, the control of the
pump according to a constant return-pipe temperature may be relevant.
FLOW
LIMIT
can be used with advantage to control the maximum circulation flow.
Constant
temperature
In a heating system where a constant temperature drop across the system is desired, constant differential
temperature can be used.
This mode requires an external temperature sensor for the second temperature measurement.
Differential
temperature
If an external controller is installed, the pump is able to change from one constant curve to another, depending
on the value of the external signal.
The pump can also be set to operate according to the max. or min. curve, like an uncontrolled pump:
• The max. curve mode can be used in periods in which a maximum flow is required. This operating mode is for
instance suitable for hot-water priority.
• The min. curve mode can be used in periods in which a minimum flow is required. This operating mode is for
instance suitable for manual night setback if Automatic Night Setback is not desired.
Constant curve
In systems with pumps operating in parallel.
The multi-pump function enables the control of single-head pumps connected in parallel (two pumps) and
twin-head pumps without the use of external controllers. The pumps in a multi-pump system communicate with
each other via the wireless GENIair connection.
