FIXED POINT REGULATION
In this confi guration, the fl ow temperature is regulated on the basis of the design indications. The heating
area is controlled by room thermostats that open and close the motorised valves. A potential free contact
in the circuit board activates or deactivates the pump and the motorised 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 room temperature must be set in the thermostats relative to the various heating areas. The fl ow
temperature to the system must be correctly set by the installer.
