Pressure gage
The pressure gage with a range from 0 to
10 bar indicates the system pressure.
Thermometer
The thermometer with a range from 0 to 160ºC constantly indi-
cates the medium temperature in the flow circuit. The temperature
is recorded directly in the medium to minimize the reaction time.
The sensor is inserted in a protective pipe so that it can be
exchanged without having to empty the system.
The ball valve allows the return line to be split between the collector and the heat accu-
mulator. The special ball cock design provides various functions. If the handle is pointing
in the direction of flow the system medium can circulate. An integrated check valve stops
osite direction and also acts as a gravity brake.

WILO ST 25/6-3 circulation pump, solar version
This circulation pump, included as standard in the scope
of delivery and integrated in the hydraulic kit, covers a
large delivery range.
The required operating point can be preselected using
one of the three levels.
A defective pump can be replaced without having to
empty the system using the stop cocks on the suction
side (Setter Inline UN) and the pressure side (ball valve).
SETTER Inline UN balancing valve
stment at the balancing valve allows the required delivery
adapted to system requirements. The proven combination
alve and flow indicator in one housing in the hydraulic kit
es means that no additional measuring components are

his does away with the need for correction curves.
nection flange on the outlet side is directly screwed onto
” pump connector fittings which means there are no seal
for further adapter components.
ctor ADG
The connector fitting with G
3/4” connecting thread for the expansion
vessel is connected in series with the circulation pump. This arrangement
prevents negative working pressure conditions in even critical systems and avoids reduc-
tions in the working pressure, one of the main causes of early evaporation of the medium.
Thermometer
The thermometer with a range from 0 to 160ºC constantly indicates the medium tempera-
ture of the flow circuit. The temperature is recorded directly in the medium to minimize
the reaction time.
The sensor is inserted in a protective pipe so that it can be exchanged without having to
empty the system.
