The adjustment fields relating to each single data are listed
below.
WARNING!
The display of the thermal data to be set contextual to
the selected scheme, i.e. the control unit displays only
the thermal data actually active for the hydraulic scheme
selected.

WARNING!
If the selected scheme has only one collector, the defaultì
value of the TS4 safety temperature will be equal to 90 °C (1),
while if the selected scheme has two collectors, the
default value of the TS4 safety temperature will be
automatically set to 140 °C (2).
In case you switch from a two-collector scheme to a scheme
with one collector and the maximum temperature TM4
greater than or equal to 85 °C, the TS4 safety temperature
will be automatically limited to the TM4 value + 5 °C.
Non è possibile impostare il valore della Temperatura di
Sicurezza TS2, TS3, TS4 ad un valore inferiore alla relativa
Temperatura Massima, poichè il valore della Temperatura di
Sicurezza è vincolato al valore della Temperatura Massima
+5°C.
In case you want to decrease the temperature value
safety, you must first decrease the value of the maximum
temperature and then act on safety temperature.
If the Safety Temperature is displayed but not the relative
Maximum Temperature, then the Safety Temperature
will be limited based on the highest Maximum Operating
Temperature in the current diagram (for example, in diagram no.
6 the TS2 safety temperature value will be limited based on
the value of the maximum temperature TM3 if this is higher
than TM4).
If the hydraulic scheme is changed, having previously
activated “Scheme 5”, all the Safety and Maximum
Temperatures will be reset to the default values set in the
factory.

WARNING!
It is not possible to set the value of the differential below
that of the relative hysteresis because the value of the
differential is limited to the value of the hyst 1 ° C.
If you want to decrease the value of the differential, you
must first ‘Lower’ the hysteresis value.

WARNING!
It is not possible to set the Hysteresis (HY) to a value higher
than that of the relative Differential (ΔT), since the value
of the Hysteresis is bound to the value of the Differential
decreased by 1 °C.
If you want to increase the hysteresis value, you must first
‘Increase’ the value of the Differential (ΔT).

WARNING!
It is not possible to set the value of the Maximum temperature
(TM) to a value higher than that of the relative Safety
temperature, as the value of the Maximum temperature is
limited to the value of the Safety temperature (TS) decreased
by 5 °C.
If you want to increase the value of the Maximum
temperature, first you have to ‘Increase’ the value of the
Safety temperature.
Integration temperature (After Heating) on probe S3
Data
Adjustment range
Default
TAH
(TEC + 3) / 20 °C .. (TM3.5) °C
50.0 °C
WARNING!
If the parameter relating to the setting of the MOD
integration operating mode has been set to nOr, it will
not be possible to set the value of the TAH integration
temperature to a value higher than that of the Maximum
Temperature TM3 minus 5 °C.
While, if the parameter relating to the setting of the MOD
integration operating mode has been set on ECO, it will
not be possible to set the value of the TAH integration
temperature to a value lower than that of the Economy
TEC temperature plus 3 °C and to a value higher than
that of the Maximum Temperature TM3 minus 5 °C.
Since the TAH integration temperature value is bound
to the value of the maximum temperature TM3 minus 5
°C and to the value of the Economy temperature plus 3
°xC (if MOD set on ECO), in case you want to decrease
the value of the maximum temperature TM3 to below
the value of the TAH integration temperature set, first
decrease the value of the TAH integration temperature
and then act on the Maximum Temperature TM3.
The same consideration must be made if you want to
increase the value of the Economy TEC temperature
above the value of the TAH integration temperature
set, you must first increase the value of the TAH
integration temperature and then act on the Economy
TEC temperature.
