I.E. A boiler that shows “Cn” “00” “3B” in this step means that is a boiler type 00 (with
pressure switch) and it is confi gured with 3 what means that the heating circuit is fl oor
heating (SU), its time to stop the pump after heating switch off is greater than 1 minute
and the pump cycling option is activated. Looking “b” it can be known that must be
connected a probe with curve type B.
- Step 2. Latest Faults.
Shows an historical with
ten last faults of the boiler. At fi rst its shown “hF”
(historical fault) and the number of faults occurred
since last time fault clean alternately. Later using
right knob is selected different faults. It shows
from “F0” to “F9” and the number of occurred fault
(“XX”) also alternately. If it shows “- -“ means that
somebody has entered in the fault menu from TAS
Control.
- Step 3. Type of boiler.
It shows alternately “ti”
and the number of the type of boiler selected. If
the value stored is 00 to 03 means that the boiler
has presotat and if the value is 04 to 08 means
that it has pressure sensor. With the right knob at
the summer position, the value stored is shown
and using this knob we can select the desired va-
lue, to store it just push the main board button and
“- -” will be displayed meaning that
the
value
is stored
- Step 4. Type of heating circuit (radiators or
fl oor heating).
The display will show CA as it’s
shown in the picture and it will alternate between
this CA and the selected option, RA (radiator) or
SU (fl oor heating). Using right knob (CH) RA (ra-
diators) or SU (fl oor heating) can be selected. In
case fl oor heating (SU) is selected, the set point
must be stored. Using the right knob (CH) it can
be selected the value between 40 and 60 ªC and
using the main board button the value will be stored and the display will show “- -
”again to indicate that the value has being stored. When this option (SU) is chosen,
the right knob (CH set point) won’t be able to select the CH set point in normal opera-
tion; it will be always the stored value in the confi guration menu.
