In the graph below, the curves have been divided into<br />
two groups:<br />
– Low-temperature systems<br />
– High temperature systems<br />
The two groups are divided according to the different<br />
point of origin of the curves, which for high-temperature<br />
systems is higher than 10°C, a correction usually made to<br />
the delivery temperature in these types of systems during<br />
climatic adjustment.<br />
4.2.4 Room Influence Proportional<br />
Turn the selector and set the most suitable value, then press<br />
the selector to confirm. The influence of the room sensor<br />
can be adjusted to a value between 20 (maximum influence)<br />
and 0 (no influence). In this way, the contribution of the room<br />
temperature to the delivery temperature calculation can be<br />
adjusted.<br />
4.2.5 Max T<br />
Turn the selector<br />
press the selector<br />
4.2.6 Min T<br />
Turn the selector<br />
press the selector<br />
then set the most suitable value and<br />
to confirm.<br />
then set the most suitable value and<br />
to confirm.<br />
4.2.7 Thermoregulation logic<br />
Turn the selector then set the most suitable value and<br />
press the selector to confirm.<br />
Turn the selector and select:<br />
0 Classic.<br />
1 Smart Smart temperature control (in this mode, the water<br />
flow set-point is calculated using the information provided<br />
in parameter 4.7 Zone regulation parameters)<br />
4.2.8 Quick night setback<br />
Turn the selector then set the most suitable value and<br />
press the selector to confirm.<br />
Turn the selector and select:<br />
0 OFF.<br />
1 ON.<br />
4.2.9 Heat request mode<br />
Turn the selector then set the most suitable value and<br />
press the selector to confirm.<br />
Turn the selector and select:<br />
0 Standard.<br />
1 RT Time Programs Exclusion (In this mode, the heat requests<br />
generated by the RT remain active also during the<br />
night-time period in programmed mode).<br />
2 Forcing Heat Demand (The activation of this function generates<br />
a constantly active heat request).<br />
Repeat the steps described previously to set the values for zone<br />
2 (where present), by selecting the 5 Zone 2 parameters menu.<br />
NOTE:<br />
For correct operation of the temperature adjustment types: 2.<br />
Room sensor only: 3. Outdoor sensor only: 4. Room sensor plus<br />
external sensor, parameter 1.0.6 Thermoregulation should be<br />
set to value 1, or the AUTO function must be activated.<br />

4.5.2 Thermoregulation<br />
Press the selector , turn the selector and set the type of temperature<br />
control installed:<br />
0 ON/OFF Thermostat (Fixed water flow set-point specified<br />
in Par. 4.5.0 T Set Cool).<br />
1 Fix Flow T (Fixed water flow set-point specified in Par. 4.5.0<br />
T Set Cool).<br />
2 Outdoor T Only (Water flow set-point according to the outdoor<br />
temperature).<br />
4.5.3 Slope<br />
Press the selector . Turn the selector and set the curve on<br />
the basis of the type of cooling system.<br />
Press the selector to confirm.<br />
– Fan coil units (curve from 18 to 33).<br />
