CLIMATIC REGULATION WITH EXTERNAL PROBE AND ROOM PROBE
The most eff ective regulation system envisions the use of an external probe through which the fl ow
temperature to the system is varied in relation to the climatic curve set and an internal room probe for
compensation. Incorrect setting of the climatic curve, the presence of internal heat intake not envisioned
or other factors can make the room temperature vary with respect to the value wanted by the fi nal user.
To compensate this, the room probe allows to correct the fl ow temperature to the system in order to reach
the desired room temperature.
This probe must be positioned in an enabling point away from heat sources, which could alter the regulation
at a height of about 1.5 m from the ground.
Moreover, the probe, measures in a unique point of the home and the fact that also the other rooms
have the same temperature value depends exclusively on a correct design and commissioning of the
system.
In this confi guration, the heating fl uid continues to fl ow with constant fl ow rate inside the piping, i.e. the
only thing that varies is its temperature. The pump is therefore only stopped when eff ectively less heat is
requested, i.e. the external temperature is very near to the internal comfort room temperature.
The fi nal user makes the day/night/anti-freeze temperature and the
weekly programming.
The fi nal user has the possibility to exclude the heating in the summer phase. With winter setting, the
heating system is active, with the summer setting it is excluded.
