5 1 Entering access code 222 turn the encoder clockwise to select 234 and press
the MENU/OK button
5 2 ZONE 2 SETTING
5 2 0 Heating appliance temperature value
setting
0 = from 20 to 45°C (low
temperature)
1 = from 35 to 85°C (high
temperature)
1 select in the appliance type base
5 2 1 Basic heating control type selection type

connected
0 = xed ow temperature
1 = device On/O
2 = ambient sensor only
3 = external sensor only
4 = ambient sensor + external
sensor
0 To activate the Thermoregulation press the SRA
button. The display lights up the SRA symbol
5 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.
see graph on the previous page
5 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.
5 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.
5 2 5 Zone 2 heating maximum temperature
setting
35 to + 82°C 82 if parameter 520 = 1
20 to + 45°C 45 if parameter 520 = 0
5 2 6 Zone 2 heating minimum temperature
setting
35 to + 82°C 35 if parameter 520 = 1
20 to + 45°C 20 if parameter 520 = 0
