monitors the boiler conditions and ensures a very reliable sup-

the boiler will temporarily switch off (depending on the nature
of the circumstances), and then after a short while simply try
again.

The control panel of the Avanta Plus has 4 function keys and a

three minutes with the “boiler in stand-by mode”, only one
dot is lit. With the “boiler operating”, two dots are displayed.

Press any key and the current boiler status and operation
code will appear in the display.
