FlowGuard
The FlowGuard FLG (fig. 4-20,
16 41 02
) is available as an
accessory. It
is a regulating valve with integrated flow indicator
which can be used to set the flow rate through the solar panel
array. The display range is 2… 16 l/min.
1. Insert the seal in the flow connection (see fig. 4-19).
2. Mount the FlowGuard, and screw it tight.
3. Fit the seal and insert the push-in fitting in the inlet of the
FlowGuard.
4. Insert the prepared flow pipe into push-in fitting in the
FlowGuard.
4.2.3 Installing temperature sensor
1. Bend over the contact springs on both sensors (return
temperature sensor, storage tank temperature sensor) and
insert into the sensor tube.
2. Position the return flow temperature sensor in the sensor tube
at approx. 130 cm insertion depth (cable tie).
3. Position the storage cylinder temperature sensor in the
sensor tube at approx. 70 cm insertion depth (cable tie).
4. Push the sealing plug into the well, and run the cables.

CAUTION!
The storage temperature sensor of the boiler
control must never be immersed more than
75 cm into the sensor immersion sleeve. A sen-
sor that is inserted too deeply can lead to over-
heating of the consumption water section, as
well as a "hang-up" of the control unit during the
storage cylinder charging phase.
