once to access the PARAMETERS MODE. In
this situation the pre-set functioning values
can be varied. e rst two gures indicate the
number of the parameter, the last two give the
setting value. Proceed as follows to modify the
boiler settings:

The boiler functioning modes are indicated
successively:
- press the MODE key once to access the
parameters mode;
- select the parameter to be modied using the
STEP key;
- change the value by acting on the + or - keys;
- press the STORE key to memorise the new
value;
- press MODE to make the new value eective.
Parameters that can be modied by the user.

4 Maximum CH ow temperature 20°C 85°C 85°C
Parameter 1: allows to set the temperature of the
DHW if controlled with the NTC probe.
Parameter 2: allows to activate or exclude the
production of DHW. From factory setting the
production of DHW is excluded.
Parameter 3: allows to exclude functioning
in system CH mode (Summer)or to enable
it (Winter). From factory settings the system
central heating is active.
Parameter 4: allows to set the CH flow
temperature. If the external temperature probe
is connected to the boiler, the electronics
automatically determines the ideal temperature
value of the system water. This parameter
represents the maximum temperature that the
CH system ow water can reach.
info MODE. Press the MODE key twice to access
the INFO mode. In this situation it is possible to
display and control the instant functioning values
without, however, making variations. e rst
two gures indicate the step number, the last two
give the setting value.
For example, if these values
are read on the display it
