4.5.3 Slope
Press the OK button. Turn the knob and
set the curve in relation to the type of
cooling system, then press the OK but-
ton.
- Fan Coil (curves from 18 to 33)
- Underfl oor (curves from 0 to 30)
The checking process for the suitability
of the curve requires a long period of
time during which several adjustments
may be necessary.
When the outdoor temperature rises
(summer), three conditions may arise:
1. The temperature of the room may
rise, indicating that a gentler curve
should be set;
2. The temperature of the room may
fall, indicating that a steeper curve
should be set;
3. The temperature of the room re-
mains 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 tempe-
rature value.
IMPORTANT:
If the room temperature is higher than
the desired value, the curve must be
shifted downwards decreasing the pa-

meters 4.5.3. If the room temperature
is too low, the curve should be shifted
upwards increasing the pameters 4.5.3.
If the temperature of the room corre-
sponds to the desired value, the curve
is correct.
In the graph below, the curves have
been divided into two groups:
- fan coil systems (graph A)
- under-fl oor systems (graph B)
Press the OK button. Turn the knob and
select:
4.5.4 Off set
Press the OK button. Turn the knob and
set the most suitable value. Press the OK
button to confi rm.
Turn the knob and select:
4.5.6 Max T
Press the OK button. Turn the knob and
set the most suitable value according to
zone temperature range (see parameter
4.5.1), then press the OK button.
Turn the knob and select:
4.5.7 Min T
Press the OK button. Turn the knob and
set the most suitable value according to
zone temperature range (see parameter
