Commissioning
In the graph below, the curves have been divided into
two groups:
– Low-temperature systems
– High temperature systems
The two groups are divided according to the different
point of origin of the curves, which for high-temperature
systems is higher than 10°C, a correction usually made to
the delivery temperature in these types of systems during
climatic adjustment.
4.2.4 Room Influence Proportional
Turn the selector and set the most suitable value, then press
the selector to confirm. The influence of the room sensor
can be adjusted to a value between 20 (maximum influence)
and 0 (no influence). In this way, the contribution of the room
temperature to the delivery temperature calculation can be
adjusted.

a constantly active heat request).
Repeat the steps described previously to set the values for zone
2 (where present), by selecting the 5 Zone 2 parameters menu.
NOTE:
For correct operation of the temperature adjustment types: 2.
Room sensor only: 3. Outdoor sensor only: 4. Room sensor plus
external sensor, parameter 1.0.6 Thermoregulation should be
set to value 1, or the AUTO function must be activated.
