9.5 Regulation with constant and proportional
differential pressure depending on the water
temperature
This is set by means of the control panel on the cover
of the Dialogue
The set point for the head of the circulator is reduced
or increased depending on the water temperature.
The temperature of the liquid may be set at 80°C or
at 50°C.

in the This type of regulation is particularly indicated:

in systems with a variable flow rate (two-pipe
heating systems), where a further reduction of the
circulator performance is ensured depending on
the lowering of the temperature of the circulating
liquid, when there is a lower demand for heating.

In systems with a constant flow rate (systems with
single-pipe and underfloor heating), where the
performance of the circulator can be regulated
only with the function influenced by temperature.
