The fan is switched on and off by means of a switch (not included in the device) being a part of the building’s electrical system.
The fan is switched on and off by means of a switch (not included in the device) being a part of the electrical installation of the building, but it will turn off after the time set by a potentiometer on the PCB has elapsed. The minimum delay is 3 minutes, the maximum - 30 minutes. Time delay adjustment is smooth.
The humidity sensor detects moisture in the range of 40% to 90% relative humidity. The fan – depending on the connection solution to the network – can be launched automatically or manually. AUTOMATIC START: the device switches on when the air humidity level exceeds the value set on the H-potentiometer and it switches off after passage of time (defi ned on the T-potentiometer) counted from the moment of humidity level decerease.
MANUAL START: the fan is activated by the switch being part of the building’s electrical system (not included in the device) or a separate switch intended for fan. After turning off the switch, the device (as in the fi rst case) switches off after the time specifi ed on the T-potentiometer, if the moisture level in the room is below the level set on the H-potentiometer. The moisture detection system is the master system.
