Regulation of the external sensor (fig.
25/a)
If an external sensor is installed, the value
of the output temperature is automatically
chosen by the system, which quickly adjusts
the environmental temperature on the
basis of the external temperature. If you
wish to change the value of the temperatu-
re, increasing or decreasing that calcula-
ted automatically by the electronic card,
proceed as indicated in the preceding para-
graph. The level of various correction of a
value of temperature proportional calcula-
ted. The display will be as shown in fig.

TO SWITCH OFF THE BOILER (fig. 24)
In the case of a short absence, press the
key ( ) of the controls (pos. 2). The

blocked. If the boiler is not used for a pro-
longed period, it is advisable to disconnect
the electricity supply, by switching off the
main switch of the system, and to close the
gas tap and, if low temperatures are expec-
ted, to completely empty the hydraulic cir-
cuits to avoid pipes being broken by the for-
mation of ice in the pipes.

When there is a functioning anomaly, the
display shows an alarm and the blue lumi-

If the water pressure detected is lower
than 0.5 bar, the boiler will stop and the
display will show "ALL 02". Proceed with
the pressure restoration until the pres-
sure indicated by transducer is between
1 and 1.5 bar.
If it is necessary to repeat the system
