0 = from 20 to 45°C (low
temperature)
1 = from 35 to 85°C (high
temperature)

0 = xed ow temperature
1 = device On/O
2 = ambient sensor only
3 = external sensor only
4 = ambient sensor + external
sensor

button. The display lights up the SRA symbol
4 2 2 Slope 0_2 to 3_5 1_5
If the external sensor is used, the boiler
calculates the most suitable heating ow
temperature taking the external temperature
and the type of appliance into account.
The type of curve must be chosen according
to the type of appliance radiator and the
heat losses present in the building.
4 2 3 Parallel shift - 20 to + 20 0
To adapt the thermal curve to the appliance requirements, it is possible to perform a parallel shift of the curve in order to alter the calculated
ow temperature and therefore the ambient temperature.
The shift value between - 20 and + 20 is shown on the display. Each level corresponds to a 1°C increase in the ow temperature in relation
to the initial setting.
4 2 4 Compensation 0 to + 20 20
if setting = 0, the temperature taken from the ambient sensor does not aect the calculation of
the setting. If setting = 20, the temperature taken has maximum inuence on the setting.
4 2 5 Zone 1 heating maximum temperature
setting
35 to + 82°C 82 if parameter 420 = 1
20 to + 45°C 45 if parameter 420 = 0
