Hydronic Module (Fig. 9/10) - Olimpia splendid SHERPA Serie Manual De Instrucciones Para La Instalación, Uso Y Mantenimiento

The SHERPA units are equipped with an integrated
hydronic module
controlled that allows fast installation with the aid of a few
external components. The SHERPA units, on the other
hand, do not have a circulation pump and expansion
vessel.
For this reason, they must be provided outside. In any case,
all the necessary protections and valves are to be inserted
in the water circuit inside the unit.
Refer to Figure 9 for the exact connection of the water
pipes. Figure 10 describes the integrated components in

channelled to the outside of the machine using the
pre-cut holes (see Fig. 4). In this case, it is necessary to
provide an open drain funnel.

The user interface allows to select between 6 pressure levels in 2 control modes:
- 3 constant pressure/power curves (CP)
- 3 proportional pressure curves (PP)
Min flow=1 ; Max flow=3
''Set Up'' procedure :
1) Factory pre-setting
2) Push the button 10 sec
3) With each push the setting changes
4) After 10 sec not pushing the button
5) LED 1 or 2 or 3 is permanently
