Warning non-return valve
non-ret. valve
selection„Yes“, „No“
factory setting „No“
This message is shown if between 10 p.m. and 5.00 a.m. a
store is loaded.
The alam message is released, when the condition men-
tioned above is fulfilled for at least 1 minute. This prevents
the alarm message from being released by short-term
disturbances.
Warning „
D
T too high“
D
T too high
selection„Yes“, „No“
factory setting„No“
This message is shown, if solar loading has been carried out
for a period of 20 minutes with a differential higher than
50 K.
Error message Digital Sensor
If the communication between the controller and the
sensors breaks down (60 s) or if the measured value is
outside the given range (dV < 0 l/min or dV > 20 l/min //
D
p < 0 bar or
D
P > 13 bar), the sensors are automatically
reset (power supply is switched off). The communication
and the measured value are checked again. If this is without
success, the sensor is defective. Control of the system is not
interrupted, but monitoring functions such as heat quantity
measurement, monitoring of pressure and flow rate will no
longer be carried out.
Error message flow rate
flow rate
selection „Yes“, „No“
factory setting „No“
If no flow rate is measured within 10 seconds after the solar
ciruit has been commissioned (dV > 0 l/min), the reset of
the digital sensors is carried out. If no flow rate is measured
after this, an error message is shown.
The threshold which is to be monitored has to be adju-
sted (factory setting 0,7 bar). If this value is underrun, the
message is generated and the system is shut down until the
system pressure exceeds the switch-off threshold (factory
setting 1,0 bar).
Error message Leakage

selection „Yes“, „No“
factory setting „Yes“
on at
adjustment range 1,5 ... 5,5 bar
factory setting 5,5 bar
off at
adjustment range 1,0 ... 5,0 bar
factory setting 5,0 bar
This message is displayed, if the system pressure is too high.
The threshold which has to be monitored is set (factory
setting 5,5 bar). If this value is exceeded, the message is
generated and the system is shut down or blocked until the
system pressure falls below the switch-off threshold (factory
setting 5,0 bar).
