commissioning
Auto function
This is a function which enables the boiler to automatically adapt
its operation routine (the temperature of the radiators) 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 adjustments menu).
To activate the function, press the A
UTO
button .
Example 1:
S
INGLE ZONE SYSTEM
(

TEMPERATURE
)
WITH ON
/
OFF ROOM
T
HERMOSTAT
:
In this case the following parameters must be set:
4 21 - Activation of temperature adjustment using sensors
- Select 01 = Basic temperature adjustment
2 44 - 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.

OUTDOOR SENSOR
:
In this case the following parameters must be set:
4 21 - Activation of temperature adjustment using sensors
- Select 03 = outdoor sensor only
4 22 - Temperature adjustment curve selection (see page 39)
- Select the relevant curve according to the type of
system, installation, heat insulation used in the building,
etc.
4 23 - 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).

OUTDOOR SENSOR
In this case the following parameters must be set:
4 21 - Activation of temperature adjustment using sensors
- select 04 = outdoor room sensor
4 22 - Temperature adjustment curve selection (see page 39)
- Select the relevant curve according to the type of
system, installation, heat insulation used in the building,
etc
4 23 - 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 24 - 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).
