The 0–10 V signal controls the boiler supply temperature. This control
2
modulates on the basis of flow temperature. The output varies between
the minimum and maximum value on the basis of the flow temperature set
point calculated by the controller.

The 0 - 10 V signal controls the boiler output. This control modulates on
the basis of the heat output. The minimum output is linked to the boiler's
modulation depth. The output varies between the minimum and maximum
value on the basis of the value defined by the controller.
Tab.26
With the Diematic Evolution mounted in the master boiler it is possible to
manage up to 7 boilers equipped with the Inicontrol 2 in cascade. The
system sensor is connected to the master boiler. All the boilers in the
cascade are connected by an S-BUS cable. The boilers are automatically
numbered:
B
C
There are two options for cascade control management:
