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 as described under C, 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 „3.2. - Manual“ on page 22

CAUTION
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 optimised if necessary.
Performing maintenance:
- Check the date and time (see „6.24. - Time and date“ on page 42)
- Assess/check plausibility of analyses (see „2. - Statistics“ on page 21)
- Check the error memory (see „2.4. - Message log“ on page 21)
- Verify/check plausibility of the current measurement values (see „1. - Measurement values“ on page 21)
- Check the switch outputs/consumers in manual mode (see „3.2. - Manual“ on page 22)
- Possibly optimise the parameter settings
