PRODUCT DATA

Terminal block (standard version, no part index suffix). Models with terminal blocks should be connected according to the wiring diagram in Fig. 2. The bathroom extractor fan is operated by means of a separate switch, which is part of the building electrical installation (not part of the appliance). Humidity sensor and timer (part name suffix “DH”). Models equipped with humidity sensors (hygrostat) and stop delay (timer) should be connected according to the wiring diagram in Fig. 3 or 4. The operation of the bathroom extractor fan will depend on the power supply connection method. When connected as shown in Fig. 4, the bathroom extractor fan starts automatically when the air humidity exceeds the set value. It is switched off when the humidity drops below the set value and after the time of the set stop delay has elapsed since the humidity drops.

If connected according to Fig. 3, in addition to automatic operation, it is possible to manually start the bathroom extractor fan using a light switch or a separate switch for the bathroom extractor fan. If the light or the bathroom extractor fan is off, as in the first case, the appliance will stop after the stop delay time set with the potentiometer has elapsed, provided that the humidity level in the room is below the level preset on the potentiometer. The humidity detection system is the master system. The humidity sensor operating range is 40% to 90% of relative air humidity. The system is additionally equipped with a timer.

The stop delay time can be set with a potentiometer knob on the electronic module of the stop delay timer. The minimum stop delay time is 3 minutes with the potentiometer knob rotated counterclockwise. Turn the potentiometer knob clockwise to set a longer stop delay time accordingly. The maximum stop delay time is 30 minutes. The stop delay time regulation is smooth. The fan stop delay time is counted from the time of switching off the light or a separate switch to which the appliance is connected or from the time of humidity drop set on the humidity sensor potentiometer.

ATTENTION:
When the green diode located in the electronic system is on, it means that the humidity level in the room is higher than the preset on the potentiometer controlling the humidity level adjustment. As long as the diode is on, the fan will not start counting down the stop delay after which the fan is switched off. It will take place only after the humidity level in the room drops and the green diode goes off.

INSTALLATION

The bathroom extractor fan should only be installed, connected to electrical mains and commissioned for use by qualified personnel per applicable laws!
