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 adjustments menu).
To activate the function, press the A
UTO
button.
Example 1:
Single zone system (high-temperature) with on/off room
Thermostat:
In this case the following parameters must be set:
4 21 - Activation of temperature adjustment using sensors
- Select 1 = 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.
Example 2:
Single zone system (high-temperature) with on/off room
Ther outdoor sensor:
In this case the following parameters must be set:
4 21 - Activation of temperature adjustment using sensors
- Select 3 = outdoor sensor only
4 22 - Temperature adjustment curve selection
- 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 modi
fi
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 cont
outdoor sensor
In this case the following parameters must be set:
4 21 - Activation of temperature adjustment using sensors
- select 4 = outdoor room sensor
4 22 - Temperature adjustment curve selection
- 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 buttons 8 which, with the
Auto function activated, is used to shift the curve in a
parallel manner.)
4 24 - In
fl
uence of room sensor
- used to adjust the in
fl
uence the room temperature has
on the calculation of the set-point
fl
ow temperature (20 =
maximum, 0 = minimum).
