11.1.2 Regulation with Constant Differential Pressure
In this regulating mode the differential pressure is kept constant,
irrespective of the demand for water,
The Hs set point may be set from the display.
Regulation indicated for:
– Heating and conditioning plants with low load losses
– Single-pipe systems with thermostatic valves
–
Plants with natural circulation
– Primary circuits with low load losses
– Domestic water recirculating systems with
thermostatic valves on the rising columnsi
