5 PRODUCT DATA
Terminal block (standard version, no part index suffix). Models with terminal block should be connect-
ed 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 sensor (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 by means of 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 counterclock-
wise� 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 regulation� The fan stop delay
time is counted from the time of switching off the light or a separate switch to which the appliance is
