14.5 ACCESSORIES NOT INCLUDED IN THE SUPPLY

14.5.1 EXTERNAL SENSOR

The External Probe, supplied as an accessory, can be
connected to the boiler as illustrated in the figure to the side.
The following procedure is used to set a parameter, called
room influence which is used to determine the importance
of the ambient temperature with respect to the external
temperature and vice-versa (the factory setting is 50%-50%).
E.g.: if the ambient influence is set to 60%, the influence of
the External Probe will consequently be 40% (the greater the
set value of ambient influence, the lesser the influence of the
External Probe will be in proportion, and vice-versa).
The following procedure is used to set ambient influence:

14.5.2 CONNECTING AN EXTERNAL STORAGE BOILER

(for models 1.12 - 1.18 - 1.24 - 1.32)
The heating-only boilers, models 1.12 - 1.18 - 1.24 and 1.32 can be connected to an external storage boiler as they are factory-
fitted with a powered three-way valve. Connect the storage boiler to the water supply. Connect the DHW priority NTC sensor,
supplied as an accessory, to terminals 9-10 of the M2 terminal block. The sensitive element of the NTC probe must be inserted in
the holder provided on the storage boiler. To adjust the temperature of the DHW see section 3.

The anti-legionellosis function is NOT ENABLED. To enable it, set parameter 1640 as described below.
To activate the ANTILEGIONELLOSIS function, proceed as follows:
• Access MENU 2 as described in section 14.2.1.
• B Temps / mode hot water
• B Periodically or Fixed weekday then choose one of the two items and
Choose Periodically to enable the function once a week on the set day and at the set time. To set the day and time, use the same
procedure described above: set parameter 1641 to establish which days (from 1 to 7) the function must activate and parameter
1644 to set the starting time of the function.
Choose Fixed weekday to enable the function once a week on the set day and at the set time. Set parameter 1642 to establish
the day of the week (from Monday to Sunday) on which the function must activate and parameter 1644 to set the start time of the
function.
