Defects and Maintenance
E 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 specifications: 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 exchange it. Then first recommission the controller
and check the function of the switch outputs in manual
mode as described under D 4.2.
E 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 D 7.2)
- Assess/check plausibility of analyses (see D 7.4)
- Check the error memory (see D 7.5)
- Verify/check plausibility of the current measurement values (see D 6)
