Press the OK button. Turn the knob and se-
lect:
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 period of time dur-
ing which several adjustments may be nec-
essary. 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 main-
tains the room temperature 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 val-
ue. 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
temperature 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 val-
ue, then press the OK button. The infl uence
of the room sensor can be adjusted to a val-
ue 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 val-
ue, 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.
Turn the knob and select:
4.2.9 Heat request mode
Turn the knob and select:
- Standard
. RT Time Programs Exclusion
(RT is active also during night periods )
- Forcing Heat Demand
(Activation of the function generates an
heat demand “always on” )
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 12.1.1 must be set to value
1, or the function SCI must be enabled.
