SETTING THE CLIMATE CURVE Kt
To set the climate curve Kt, access menu 2 as described in section 14.2.1 and proceed as follows:
.
• B 720 (Heating curve slope)
• B (from 0.10 to 4)
Select the climate curve from among those available, see the curve chart in annex "SECTION" E at the end of this manual (the
preset curve is 1.5).

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

15. SPECIAL FUNCTIONS

Available functions are:
• Manual control (301) - Options: 25 - 90 (°C) In this mode the boiler operates at the set temperature value.
• Chimney sweeper (programme row 303) - Options: Full load (maximum thermal power of the boiler), Part load (reduced
thermal power), Full heating load (maximum thermal power in the heating mode).
• Controller stop function (304) - Options: from 100% (maximum thermal power) to 0% (reduced thermal power). This function
facilitates gas valve calibration operations.
• Deaeration function (312) - Options: On (function enabled) - Off (function disabled). See section 15.1 "System gas extraction
function".
The procedure used to enable these functions is the following:

E.g.: turn knob B to enable the CALIBRATION function
(programme row 304), press knob B, the function is now active
and preset to 100% (the boiler is at its maximum thermal
power). Press the knob and turn it to select the required power
percentage (0% corresponds to the reduced thermal power
level).
To manually interrupt the function, repeat the procedure described above. When the function is disabled, " off" is shown on
the display.
