ON = Electricity supply to boiler is on
OFF =
Electricity supply to boiler is on but not
ready for functioning. However, the protec-
tion functions are active.
SUMMER MODE KEY
When this key is pressed, the boiler functions only
when D.H.W. is requested
(function not available)
WINTER MODE KEY
When this key is pressed, the boiler provides hea-
ting and D.H.W.
D.H.W. TEMP KEY
When this key is pressed, the temperature of the D.H.W.
is shown on the display
(function not available)
HEATING TEMP KEY
The first time the key is pressed, the temperature of
heating circuit 1 is shown.
The second time the key is pressed, the temperatu-
re of heating circuit 2 is shown.
The third time the key is pressed, the temperature
of heating circuit 3 is shown (3-zone system).
RE-SET KEY
This allows for restoring functioning after a functio-
ning anomaly.
INCREASE AND DECREASE KEY
By pressing this key the set value increases or
decreases.
