To set the temperature adjustment parameters, simultaneously
press and hold the back “

appears on display. Turn the knob to enter the technical code
(234), then press OK; the display will show

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.

The checking process for the suitability of the curve requires a long
period of time during which several adjustments may be necessary.

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 Off set
Press the OK button.
Turn the knob and set the most suitable value. Press the OK button
to confi 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 diff erent point of
origin of the curves for high-temperature systems, which is +10°C,
a correction which is usually made to the fl ow temperature in this
type of system, during climatic adjustment.
Turn the knob and select:
4.2.4 Room Infl uence Proportional
Press the OK button.
Turn the knob and set the most suitable value, then press the OK
button. The infl uence of the room sensor can be adjusted to a
value between 20 (maximum infl uence) and 0 (no infl uence). This
means the contribution of the room temperature to the fl 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.
