Thermoregulation
To set the temperature adjustment parameters, simultaneously
press and hold the back “
“ and “OK” buttons until “Enter code”
appears on display. Turn the knob to enter the technical code
(234), then press OK; the display will show Technical area.
Turn the knob and select
- Complete Menu.
Press the OK button.
Turn the knob and select:
4 Zone 1 Parameters
Press the OK button.
Turn the knob and select:
4.2 Zone 1 settings
Press the OK button.
Turn the knob and select:
4.2.0 Zone 1 Temperature range
Press the OK button. Turn the knob and select the temperature
range:
0 low temperature
1 high temperature
Press the OK button to con rm. Turn the knob and select:
4.2.1 Thermoregulation
Press the OK button.
Turn the knob and select the installed temperature adjustment:

Press the OK button. Turn the knob and select:
4.2.2 Slope
Press the OK button. Turn the knob and set the curve in accord-
ance with the type of heating system and press the OK button.
- low temperature system
( oor panels)
curve between 0.2 and 0.8
- high temperature system
(radiators)
curve between 1.0 and 3.5
The checking process for the suitability of the curve requires a long
period of time during which several adjustments may be necessary.

Curves graph
 ow temperature to the system
arise:
1. The temperature of the room may fall, indicating that a steeper
curve should be set;
2. The temperature of the room may rise, indicating that a gentler
curve should be set;
3. The temperature of the room remains constant, indicating that
the set curve is exactly right;
Once you have found the curve which maintains the room tem-
perature at a constant level, check the actual temperature value.
Turn the knob and select:
4.2.3 O set
Press the OK button.
Turn the knob and set the most suitable value. Press the OK button
to con rm.
NOTE:
If the room temperature is higher than the desired value the curve
must be shifted downwards. If, on the other hand, the room tem-
perature is too low, the curve should be shifted upwards. If the
temperature of the room corresponds to the desired value, the
curve is in the right position.
In the graph below, the curves have been divided into two groups:
- low temperature systems
- high temperature systems
The two groups are divided on the basis of the di erent point of
origin of the curves for high-temperature systems, which is +10°C,
a correction which is usually made to the  ow temperature in this
type of system, during climatic adjustment.
Turn the knob and select:
4.2.4 Room In uence Proportional
Press the OK button.
Turn the knob and set the most suitable value, then press the OK
button. The in uence of the room sensor can be adjusted to a
value between 20 (maximum in uence) and 0 (no in uence). This
means the contribution of the room temperature to the  ow tem-
perature calculation can be adjusted.
Turn the knob and select:
4.2.5 Maximum temperature
Press the OK button.
Turn the knob and set the most suitable value, then press the OK
button.
Turn the knob and select:
4.2.6 Minimum temperature
Press the OK button.
Turn the knob and set the most suitable value, then press the OK
button.
Repeat the steps described to set the values for zone 2 (if present),
selecting menu 5.
NOTE:
For the correct operation of the types of thermoregulation: 2. Room
T Only, 3. Outdoor T Only, 4. Room + Outdoor T, the parameter
17.1.1 must be set to value 1, or the function SCI must be enabled.
