In a C.H. installation equipped with a D.H.W.
storage tank, the hydraulic schema, shown
in fig. 29, can be used.
Note: Also in this case the remarks made in
the previous paragraph are applicable, i.e.:
the adoption of a shunt pump (Pr).
The electrical connections of the storage tank
loading pump will follow the schema shown
in fig. 26.

4.4 - ELECTRICAL AND HYDRAULIC CONNECTIONS OF C.H.

AND D.H.W. PRODUCTION CIRCUIT

Pr Shunt pump
VM2 Mixing valve
SPFS Storage tank temperature sensor
KFS Boiler temperature sensor
VFAS Flow temperature sensor

C Boiler
B Storage tank
P1 C.H. pump for direct zone
P2 C.H. pump for mixed zone
Pb Storage tank loading pump

4.5 - OUTER COMPENSATOR

On how to adjust or to program the outer
compensator, please refer to the instruction
manual supplied with the outer compensator.
In the following table we list the factory set

parameters, which are "not changeable" and
the parameters which are adjustable by the
user according to his needs.
