COSMO High ‐ efficiency pump CPH 2.0 49
Control with constant differential pressure
Adjustment for constant curve
In this control mode, the circulation
pump works with characteristic curves
and constant speed.
This control mode is recommended
for heating & air conditioning systems
with constant flow rates.
With this control mode, the differential
pressure is kept constant, regardless of
water demand.
Setpoint Hs can be adjusted via the
external display.
This control mode is recommended for:
o
Heating & air conditioning systems
with low pressure losses.
o
Single ‐ pipe systems with
thermostatic valves.
o
Plans with natural circulation.
Primary circuits with low pressure
losses.
o
Domestic water circulation with
thermostatic valves in the riser pipes.
