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
of zones controlled, the boiler adjusts its fl ow temperature
automatically.
The various corresponding parameters should therefore be set (see
Technical Area).
To activate the function, press the AUTO button.
For further information please refer to the ARISTON
temperature adjustment manual.
EXAMPLE 1:
SINGLE ZONE SYSTEM (HIGH-TEMPERATURE) WITH ON/OFF ROOM
THERMOSTAT:
In this case the following parameters must be set:
4.2.1 - Activation of temperature adjustment using sensors
- Select 04 = Basic temperature adjustment
2.4.4 - Boost Time (optional)
The wait time for the fl ow temperature increase in steps of
4°C may be set. The value varies according to the type of
system and installation.
If the Boost Time value = 00 the function is not activated.
EXAMPLE 2:
SINGLE ZONE SYSTEM (HIGH-TEMPERATURE) WITH ON/OFF ROOM
THERMOSTAT + OUTDOOR SENSOR:
In this case the following parameters must be set:
4.2.1 - Activation of temperature adjustment using sensors
- Select 01 = outdoor sensor only
4.2.2 - Temperature adjustment curve selection
- Select the relevant curve according to the type of system,
installation, heat insulation used in the building, etc.
4.2.3 - Perform a parallel curve shift if necessary, increasing or
decreasing the set-point temperature (this may also be
modifi ed by the user, using the heating temperature
adjustment knob, which, with the AUTO function activated,
is used to shift the curve in a parallel manner).
EXAMPLE 3:
SINGLE ZONE SYSTEM (HIGH-TEMPERATURE) WITH SENSYS REMOTE
CONTROL + OUTDOOR SENSOR
In this case the following parameters must be set:
4.2.1 - Activation of temperature adjustment using sensors
- select 0 = outdoor sensor + room sensor
4.2.2 - Temperature adjustment curve selection
- Select the relevant curve according to the type of system,
installation, heat insulation used in the building, etc
4.2.3 - Perform a parallel curve shift if necessary, increasing or
decreasing the set-point temperature. (This may also be
changed by the user by the encoder which, with the AUTO
function activated, is used to shift the curve in a parallel
manner.)
4.2.4 - Infl uence of room sensor
- used to adjust the infl uence the room temperature has
on the calculation of the set-point fl ow temperature (20 =
maximum, 0 = minimum).
