For IS models (fig. 34b):
JUMPER I� POSITIO� 2: (water tank with probe)
JUMPER I� POSITIO� 3: (water tank with thermostat)
JUMPER I� POSITIO� 4: (unused)
JUMPER I� POSITIO� 5: (unused)
JUMPER I� POSITIO� 6: (unused)
The boiler is supplied standard with the �umper in position 3 (water
tank with thermostat); if you wish to use an external water tank
with probe, move this �umper from position 3 to position 2 (case C).

13 - SETTING THE THERMOREGULATION

Heat ad�ustment only works with the external probe connected,
therefore, after installation, connect the external probe to the rela-
tive connections on the boiler terminal board.
This enables the THERMOREGULATIO� function.
Selecting the offset heating curve (fig. 35)
The offset heating curve maintains a theoretical ambient tempera-
ture of 20°C at external temperatures ranging from +20°C to -20°C.
The choice of the curve depends on the rated minimum external
temperature (on the geographical area, therefore) and the rated
delivery temperature (on the type of system, therefore) and must
be carefully calculated by the fitter using the following formula:
�ominal delivery T. � Tshift
TMR =
20 - min. rated external T.
Tshift = 30°C standard systems
25°C floor systems
If the calculation generates an intermediate value between two
curves, choose the nearest offset heating curve to that value.
E.g.: if the value obtained by the calculation is 1.3, it lies between
curve 1 and curve 1.5. In this case, select the nearest curve, i.e.:
1.5.
Select TMR by turning the trimmer located under the instrument
panel (fig. 4)
The settable values of TM� are:
� standard system: 1,0�1,5�2,0�2,5�3,0
� floor system: 0,2�0,4�0,6�0,8
Type of heat request
If an ambient thermostat is connected to the boiler (parameter
51 = 0 - manufacturer's default setting) (fig. 35)
The ambient thermostat makes a heat request when its contact
closes, while it stops it when its contact opens. Though delivery
temperature is automatically calculated by the boiler, the user may
manually override it. �y modifying HEATI�G on the user interface
(IG�, 4a), the HEATI�G SET POI�T will no longer be available
but �ust a value that can be set from +5 to �5°C as required. Modi-
fications to this value do not directly change delivery temperature
but affect the calculation made to automatically determine its value
by modifying the reference temperature of the system (0 = 20°C).
If a programmable timer is connected to the boiler, set parameter
51 = 1 (this parameter can only be modified from the remote con-
trol unit).
When the contact is closed, the heat request is made by the delive-
ry probe on the basis of the external temperature in order to main-
tain the rated ambient temperature at the DAY level (20 °C). When
the contact opens, it does not stop the heat request but reduces
(parallel shift) the temperature curve to the �IGHT level (16 °C).
This activates the night mode.
Though delivery temperature is automatically calculated by the
boiler, the user may manually override it.
�y modifying HEATI�G on the user interface (IG�, 4a ), the HEA-
TI�G SET POI�T will no longer be available but �ust a value that
can be set from +5 to -5°C as required.
Modifications to this value do not directly change delivery tempera-
ture but affect the calculation made to automatically determine its
value by modifying the reference temperature of the system (0 =
20°C for DAY level; 16°C for �IGHT level).

14 - ADJUSTMENTS

The boiler has already been factory�ad�usted by the manufacturer.
If a new ad�ustment is required, for example, after extraordinary
maintenance, replacing the gas valve or converting from natural
gas to LPG, proceed as follows.
Maximum and minimum power, maximum heating and slow
start must be ad�usted in the indicated sequence by qualified
staff.
- Power the boiler
� turn the function selector to OFF/RESET (digit "��")
� unscrew screws A and remove instrument panel � (fig. 4)
� turn the trimmers in the following sequence and ad�ust them until
their values correspond with those indicated in the table:
1. Max (1a) (maximum fan rpm)
2. Min (2a) (minimum fan rpm)
3. HTG (3a) (maximum heating fan rpm)
4. IG� (4a) (slow start LA) (35 KIS / 20 IS: set to 3.7=3700 rpm
25 KIS: set to 3.4=3400 rpm)
Calibration does not switch on the boiler.
When the trimmers are turned the value expressed in thou-
sands (e.g.. 2.5=2500 rpm) is indicated on the 2�digit di-
splay).
Slow start LA must be ad�usted after calibrating all the other
trimmers.
