Solar unit components
The solar kit consists of:
• solar control unit
• boiler probes and panel probe to be positioned in the
panel (by the installer)
• 24 L solar expansion vessel
• adjustable thermostatic mixing valve from 35 to 65 ° C, to
be calibrated (by the installer)
• solar circuit charging unit
• solar circuit circulation pump
The solar kit is supplied separately. It is a factory installed
and tested accessory.

• other information and data
The control unit automatically manages the outputs and in-
puts related to the type of system set according to the fol-
lowing logic:
• the PSO pump is activated with S1 - S2 > 8 °C
• the PSO pump is activated with S1 - S2 < 4 °C
Solar pump PSO
On the front part of the pump body there is a regulator that
allows to select the head according to the actual solar system
requirement.
The setting of the head value of the solar pump PSO must be
carried out with:
• the solar system working
• all distribution valves open
• utilities on
Verify that the tem-perature difference is congruent with
the project.
