6. If there occurs the boiler failure state, the failure signalisation in automatics lights up. The most
common reasons for failures and the possibilities to eliminate them are shown in chapter no.16. The user
can only eliminate the failures signed with symbol „*“. In case of electricity outage the burner is put out of
operation and after the voltage recovery in the electricity network the burner is restarted automatically.
The failure is unblocked by means of “unblocking” button in the network module.

“overheating” signal lamp lights up on boiler control panel. The thermostat can be unblocked by user in
the network module (TB). Safety thermostat switching off can be caused by several reasons, see chapter
no. 16.
8. Combustion products return flow fuse unblocking. If the boiler has been switched of by the fuse then
the “overheating” signal lamp lights up in network module. The TS fuse can be unblocked by user in the
network module.
