Sensor/actuator
test
The current values of the following sensors can be read off
here:
–
T1 temperature sensor
–
T2 temperature sensor
–
T3 temperature sensor
–
T4 temperature sensor
–
T5 collector sensor
–
T6 cylinder sensor
–
Cylinder circuit flow rate
–
Temperature limiter
–
Solar circuit flow rate
The selection button can be used to activate the following
actuators. You can then use the plus and minus buttons to
change the output/power of the pumps, the flow direction
of the shift-load switching valve or the stratification in the
cylinder.

Solar pump
–
Solar pump 2
–

–
UV5 shift-load switching valve
In addition, you can view the approximate
Solar circuit flow
rate
. The value is calculated from the pump output and rota-
tional speed.

The operating mode can be set to
Auto
,
High Flow
and
Low Flow
.
–
Auto
: The solar control attempts to maintain the spread
between the solar supply pipe and the solar return so
that the process water zone in the cylinder is charged at
65 °C. If this is not possible due to low solar radiation, the
heating zone in the cylinder is charged at 40 °C. If this is
not possible either, a spread of 10 K is attempted.
–
High Flow
: The solar control attempts to maintain the
spread between the solar supply pipe and the solar re-
turn at approx. 10 K. As a rule, this corresponds to 40 l/h
per m

collector surface
–
Low Flow
: The solar control attempts to maintain the
spread between the solar supply pipe and solar return so
that the cylinder is charged at the maximum set cylinder
temperature. As a rule, this corresponds to 15 l/h per m
