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 ow temperature
automatically.
The various corresponding parameters should therefore be set
(see adjustments menu).
To activate the function, press the auto 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 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 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 modied 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 HD
controller + outdoor sensor
In this case the following parameters must be set:
4 21 - Activation of temperature adjustment using sensors
- select 4 = outdoor sensor + 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 - Inuence of room sensor
- used to adjust the inuence the room temperature has
on the calculation of the set-point ow temperature (20
= maximum, 0 = minimum).
Note: See page 38 for details on accessing menus.
