Soler company & Palau has released a new silent exhaust fan series SILENT-100 CHZ DESIGN. The device has a built-in hygrometer and a timer to delay the fan shutdown. Switching of operating modes is carried out by microswitches on the printed circuit board.
The fan is powered by AC power, with a voltage of 220 volts and consumes only 8 watts. The connection to the network is realized by means of a screw terminal block located inside the housing. There are three clips "L"," N "and" Ls"for connecting to the network and the control button. To the terminals "L", "H" we connect 220 volts (I-phase and H-zero (neutral)). Next, we take the wire that goes from the switch to the lighting lamp and connect it to the " Ls " pin(the switch must necessarily break the phase wire). with this connection, it will work according to the following scenario: the fan will not start from the switched-on light switch if the humidity in the room is less than the threshold set by the microswitches 4 and 5 on the fan board.
When the fan is connected directly to the mains with two wires (L and H without the use of HP), the fan does not start in the initial state, but as soon as the humidity becomes more than 60 percent (set by the factory by default), it starts working and turns off 30 minutes after starting (the process is repeated again and again, when the humidity increases in a ventilated room).
