CLIMATIC ADJUSTMENT WITH EXTERNAL PROBE
The fl ow temperature to the system varies in relation to the external temperature detected and the climatic
curve set.
As there is no internal room temperature control, the climatic curve must be selected correctly.
Often the mixing unit is connected to a collector that serves diff erent heating areas
Every area is opened or closed with the aid of motorised valves controlled by the room thermostats.
A potential free contact in the circuit board activates or deactivates the pump and the mixer valve.
If at least one heating area is requested (closed contact) the mixer unit is activated (pump is on and mixer
valve active), if instead all areas are satisfi ed (contact open), the pump switches off and the mixer valve
closes.
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.
