Control board. Control panel consisting of: The main switch, safety thermostat button, the display, the group command buttons (buttons), a group of light-emitting diode pointer. K1 • With a Click enters to modify the value of the Boiler thermostat: Led L3 blinking: with buttons K2 and K3 modify the actual set value. • A long pressure enters to modify the function Winter/ Summer signalled by the led L1/L2. • In modify parameters saves the set value. K2 • With a Click enters to modify the value of the Working time of the cochlea engine: Led L7 blinking: with buttons K2 and K3 it is possible to modify the actual set value. • A long pressure activates the manual loading of the combustible for the length of the pressure activating the cochlea engine: the display shows LoAd. The procedure is possible only with state OFF. With a safety valve the loading starts after the timer T72. • In modify parameters it is possible to decrease the value and the sliding of the parameters' codes. K3 • With a Click enters to modify the value of the fan speed: Led L8 blinking: With buttons K2 and K3 it is possible to modify the actual set value. • A long pressure activated the fan at the maximum speed for the length of the pressure. The display shows UEnt. The procedure is possible only with state OFF. • In modify parameters it is possilble to increase the value and the sliding of the parameters' codes. K4 • With a long pressure ignites/extinguishes the boiler: Led L5/Led L6 on. • With a click enters the menu visualisation of the temperature values provided by the system. • In modify parameters exits without saving. K2+K3 K2+K3 With a long pressure of both the buttons it is possible to modify the combustion recipe. It is signalled by led L12-L14: with buttons K2 and K3 it is possible to modify the actual value Pr1/Pr2/Pr3. The maximum settable combustion recipes in the user menu is limited to the parameter P89. In state OFF or EXTINGUISHING, in case of alarms, pushing the button K2 or K3 it is possible to end the Visualisation. If present again after the reset, they are shown again. L2 On in modality Summer. L3 On for boiler temperature less than A03-A05. Blinking for temperature more than the above thermostats. Off for temperature more than A03.
