6.2.6 Manual operation
Exclusively for commissioning and test purposes, the system can
be switched on manually for the time period saved in the pa-
rameter "H/A". All the regulation functions are switched off and
the solar operating pump P
S
runs continuously, independent of
the system temperatures, at the set output stage.
Ɣ Pressing (>1 s) both arrow keys simultaneously activates or
deactivates manual operation.
6.2.7 FlowSensor
The FlowSensor (FLS) serves to measure the flow rate "V" and
the flow temperature "T
V
".
With the sensor connected and working:
– the measurement values "V" and "T
V
" are displayed.
– the controller operates after the filling process with the real
spread T
V
- T
R
.
If the system has detected the FlowSensor once, the display
shows an error message if a sensor is faulty or is disconnected
(see chapter 7.1 "Display of events"). The system then works in
the emergency mode without the FlowSensor.
If the controller detects a FlowSensor after a new installation or a
technician reset, the value "20" is set automatically in the param-
eter "FLS active".
The correct parameter value for the FlowSensor fitted to the
system must always be checked and adjusted if necessary
(see tab. 6-1). The Flow Sensor can be disabled by input of the
parameter value "0".
If the heating expert deactivates the FlowSensor, then no fault
signal will appear. The control system now operates without the
measured value for the flow. The feed temperature "T
V
" is set to
be equal to the solar panel temperature "T
K
".
6.2.8 Output calculation, maximum values, and yield
count
If a FlowSensor is connected, the system operating data is calcu-
lated and balanced, such as the current heat output and the solar
heat yield. The maximum and calculated values can be called up
o the display (see chap. 6.3). Values greater than "0" that have
not been deleted will continue to be displayed even after removal
or deactivation of the FlowSensors (without further updates).
CAUTION!
Uncontrolled manual operation can lead to heat loss,
excessively high storage tank temperatures and,
under certain cold situations, even to frost damage.
The manual mode cannot be activated with active "en-
hanced frost protection function" (star symbol in display
flashing - see section 6.2.10).

The balancing and calculation of the system operating
data (e.g. solar heat yield) does not replace a calibrated
thermal energy meter. These values may not be used
for invoicing heating costs or similar legally valid
accounting purposes.
