G - Defects and Maintenance
G 1 - Malfunctions with error messages
If the controller detects a malfunction, a warning
symbol appears in the display. If the error is no longer
present, the warning symbol changes to an info
symbol.
To obtain more detailed information on the error, press
the key under the warning or info symbol.
Do not try to deal with this yourself.
Consult a specialist in the event of an
error!
Possible error messages: Notes for the specialist:
Sensor x failed Means that either the sensor, the sensor input at the
controller or the connecting cable is defective.
Collector alarm Means that the collector temperature has exceeded the value
set in Menu F 6.5.
On / Off too often The solar pump was switched more than 6 times in 5
minutes.
Restart
Means that the controller was restarted, for example due
to a power failure. Check the date and time!
G 2 - Replacing the fuse
Repairs and maintenance may only be performed by a specialist. Before working on the unit,
switch off the power supply and secure it against being switched on again! Check for the absence
of power!
Only use the supplied spare fuse or a fuse of the same design with the following speci fi cations: T2A 250V.
If the mains voltage is switched on and the controller
still does not function or display anything, then the
internal device fuse may be defective. In that case,
disconnect the device, open it, remove the old fuse
and check it.
Exchange the defective fuse for a new one, locate the
external source of the error (e.g. pump) and replace
it. Then
fi rst recommission the controller and check
the function of the switch outputs in manual mode as
described under F 4.2.
