2.7 SETTING OF CONTROL PANEL
You can set 4 ways of operation:
a) Normal mode:
Mode of functioning of the boiler, temperature of supply, level of gas modulation and presence of flame are visualised.
Possible anomalies are visualized as besides from coding at page 21.
b) Mode of visualization of boiler parameters:
It is activated by pushing P1+P2 for 6s. You can visualize in order:
Heating set
- supply temperature
Domestical hot water set
- domestical hot water temperature
- water supply pressure
- heat of ignition
- nominal heat output
c) Mode of parameters setting:
It is activated by pushing P1+P2 for 9s. You visualise alternatively the number of the parameter Px and the current value.
Pushing the keys P3 and P4 is possible to see in sequence the modifiable parameters, otherwise with the keys P5 and
P6 it is possible to modify its value.
Pressing P3+P4 you can go out of the function without memorizing the changes.
Pressing P2 for 5s you go out the menu and you memorize the changes.
The available parameters are:
- P1 Power of ignition (by 0 % to 99 % of maximum value of range of regulation)
- P2 Power of heating (by 0 % to 99 % of maximum value of range of regulation)
- P3 Heating anti cycling timer (by 0 % to 99 % of 6 minutes)
- P4 oF = post-ventilation of fan off / on = post ventilation of fan on
- P5 Off = metano / on = GPL
- P6 oF = water's lack: boiler stops / on = water's lack: boiler doesn't stop, but you have to

assistance.
- P7 Minimum heating input
(0 ÷ 100 %)
- P8 oF = external sensor off / on = external sensor on
- P9 K OTC (0 ÷ 6)
- Pa type of boiler
(0 = domestical hot water and heating system boiler

- Pb type oh DHW exchanger
oF = with plates /on = with little tank
- Pc miminum of heting supply temperature.
(+15 ÷ +50) °C
- Pd
temperature of primary circuit of tank
(0: temperature of primary circuit = DHW set point
+20°C /1: temperature of primary circuit = 80°C)
d) Mode of visualisation of historical failure.
It is activated by pushing P1+P2 for 12s. You visualize alternatively the number of index failure(look at page 21).
By pushing P3+P4 you go out of the function.
By pushing P2 for 5s you can delete the historical of failure.

To increase the cyclic efficiency we suggest to set P3 (anti cycling timer) with values near to 10 and to set P7 with values
between 10 to 20.
