Zone 1 Cooling Temp Range
Press the OK button.
Turn the knob and select the temperature range:
- Fan Coil
- Underfl oor
Press the OK button.
Turn the knob and select:
4.5.2 Thermoregulation
Press the OK button. Turn the knob and set the type of tempe-
rature adjustment installed:
- 0 ON/OFF
- 1 Fix Flow T
- 2 Outdoor T Only
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 button.
- 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 condi-
tions may arise:
1. The temperature of the room may rise, indicating that a gen-
tler curve should be set;
2. The temperature of the room may fall, indicating that a stee-
per 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.
IMPORTANT:
If the room temperature is higher than the desired value, the
curve must be shifted downwards decreasing the pameters
4.5.3. If the room temperature is too low, the curve should be
shifted upwards increasing the pameters 4.5.3. If the tempera-
ture of the room corresponds 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:

4.5.1), 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
4.5.1), then press the OK button.
Repeat the steps described to set the values for zones 2 (if pre-
sent), selecting menu 5.
