14.1 Pump Wilo Yonos Para
Pic.17. Settings via operating knob
Variable differential pressure
The differential-pressure setpoint H is increased linearly over the permitted volume flow
range between ½H and H. The differential pressure generated by the pump is adjusted to the
corresponding differential-pressure setpoint. This control mode is especially useful in heating
systems with radiators, since the flow noises at the thermostatic valves are reduced.
Constant differential pressure
The differential-pressure setpoint H is kept constant over the permitted volume flow range at
the set differential-pressure setpoint up to the maximum pump curve. Wilo recommends this
control mode for underfloor-heating circuits or older heating systems with large-sized pipes as
well as for all applications with no changeable pipe system curve, e.g. boiler charge pumps.
Venting function
During automatic venting function (10min) the Pump runs alternately with high and low speeds
to help air bubble from the pump to agglomerate and to lead direct to the venting valve of the
installation.
