• Press button 14 (Figure 5.25) to confirm the val-
ue entered. The display will show the following
(Figure 5.31) for 5 seconds, then move up to
the next level.

• Press the keys 13 and 15 simultaneously (Fig-
ure 5.25) to exit the level without changing the
value (return to the previous level).
To exit the parameters menu:
• wait 15 minutes without pressing any key;
• switch off the electric power supply;
• press the 13 and 15 keys simultaneously for 5
seconds (Figure 5.25) (return to previous level).
5.16 Electrical connection of the remote
(optional)
Use the terminals indicated in Figure 5.22 to con-
nect the remote.
To connect the remote control to the boiler, refer
also to the REMOTE CONTROL manual.
The electric jumper between "A and B" must
be removed.
The path of the remote control cable must follow
the path indicated in Figure 5.22.
INSTALLATION
Make the boiler cables exit using specific cable
glands R (Figure 5.24).
5.17 Enabling operation with the
external sensor and setting the K
coefficient
The boiler is set with a K coefficient equal to zero
for boiler operation without the probe connect-
ed.
If the remote control IS CONNECTED to the boil-
er (optional), refer to Figure 5.32.
In this case, the K coefficient must be set remote-
ly.

The K coefficient is a parameter that increases or
decreases the boiler delivery temperature as the
outdoor temperature varies.
When installing the external sensor, this param-
eter must be set based on the efficiency of the
heating system to optimise the delivery tempera-
ture (Figure 5.32).
E.g. To achieve a heating system delivery tem-
perature of 60°C with an outdoor temperature
of -5°C, set a K of 1.5 (dashed line in Figure 5.32).
Sequence for setting the K coefficient
• Enter "programming mode" by pressing the 13
and 15 keys simultaneously for 5 seconds (Fig-
ure 5.33) until HiS (Boiler History) appears on
the LCD display (Figure 5.34).
