commissioning
Auto function
This is a function which enables the boiler to automatically adapt its
operation routine (the temperature of the heating elements) in line
with the outdoor conditions, in order to achieve and maintain the
requested room temperature conditions.
Depending on the peripheral units connected and the number
ow temperature
automatically.
The various corresponding parameters should therefore be set (see
adjustments menu).
To activate the function, press the A
UTO
button.
For further information please refer to the ARISTON temperature
