Defects and Maintenance
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,
open the device, 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 exchange
it. Then
fi
rst recommission the controller and check
the function of the switch outputs in manual mode as
described under 9.2.
G 3 - Maintenance
In the course of the general annual maintenance of your heating system you should also have the functions of
the controller checked by a specialist and have the settings optimized if necessary.
Performing maintenance:
- Check the date and time (see 3.1.)
- Assess/check plausibility of statistics (see 2)
- Check the error memory (see 2.6)
- Verify/check plausibility of the current measurement values (see 1)
- Check the switch outputs/consumers in manual mode (see 4.2)
- Possibly optimize the parameter settings
