Thermoregulation
To set the temperature adjustment parameters, simultaneously press
and hold the back " " and "OK" buttons until "Enter code" appears
on the 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 confi rm. Turn the knob and select:
4.2.1 Thermoregulation
Press the OK button.
Turn the knob and set the type of temperature adjustment installed:
- 0 Fixed fl ow temperature
- 1 Basic Thermoregulation
- 2 Room T Only
- 3 Outdoor T Only
- 4 Room + Outdoor T
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 accordance
with the type of heating system and press the OK button.
- low temperature system
(fl 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 pe-
riod of time during which several adjustments may be necessary. When
the outdoor temperature falls (winter) three conditions may 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 temperature
at a constant level, check the actual temperature value.
Turn the knob and select:
4.2.3 Offset
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 lower. If, on the other hand, the room temperature
is too low the curve should be shifted upwards. If the temperature
of the room corresponds with 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 based on the different point of origin of
the curves for high-temperature systems, which is +10°C, a cor-
rection 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 temperature
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 but-
ton.
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 but-
ton.
Repeat the steps described to set the values for zones 2 and 3, se-
lecting menus 5 and 6.
NOTE:
For the correct operation of the types of thermoregulation: 2.
Room T Only, 3.Outdoor T Only, 4. Room + Outdoor T, the pa-
rameter 17.1.1 must be set to value 1, or the function SRA must
be enabled.
