the reading/setting of that channel.
In the event of a malfunction, an error message
is displayed alternately with channel number
and value. See “Dealing with malfunctions” —
“Indications on the numerical display”.

to normal mode “1” the numerical display can
remain dimmed for a brief period. This can also
occur at extremely low outdoor temperatures.

Pressing the “Extra hot water” button raises the
boiler temperature to about 60°C, giving
increased water capacity for about 24 hours. In
this mode, the built-in lamp is constantly lit.
Pressing the button again gives a permanent
function which raises temperature of the hot
water at regular intervals. In this mode, the
built-in lamp flashes.
Pressing the button again resets the above
functions.
