12-SETTINGS MENU
AUX INPUT (using one of the following parameters excludes the other)
The auxiliary input allows choosing the system configuration type based on which the stove is connected.
To enter the function press:
from the Settings menu- press ok (E key), press the D (arrow) key and scroll up to the Aux Input item and press OK (E key). Using the “C”
and “D” keys select the desired heating system type and press ok with the “E” key.
It is possible to connect the following to the auxiliary input:
Room thermostat 2
External probe
Boiler probe
Boiler thermostat
Puffer probe
Puffer Thermostat
Note: The boiler probe/thermostat choice implies the three-way aux output designation.
The puffer probe/thermostat choice implies the pump aux output designation.
• Room Therm.2
The stove heat request may take place from any part of the room probe or from the “Termostato Amb 2” (Room thermostat 2) installed
in a room that is different from the one where the stove is positioned and is connected to terminals 1 and 2 of the back terminal board.
Contact closing the terminal kicks off the heat request.
Notes: Installation of this thermostat is optional, the stove can also operate without it. Since the contact is N.O., the room probe is the
only heat request command.
Possible active weekly programming does not act on Room Thermostat 2 but rather on the probe on board the stove.
