The EOL range of exhaust duct fans are ideal for bathrooms and toilet applications. These thinnest models on the market with a very attractive design are the best solution to keeping the air fresh and clean in your house. The range can be extended with the electronic control systems with photocell, timer or humidity sensor and the fans are compatible with all European and international standards.

Technical data:

The fans extended with the electronic control systems have a mounted timer. Fan activation depends on the control system.

E1- photocell (pic.1) starting the fan is doneby the change in the light intensity in the area where the fan is installed. The switches 1,2,3 are for setting the time of the fan activity. Given lengths of time can be set by moving the switches according to (pic.2).
The 4 switch is for setting two automatic cycles of the fan activity.
I. The switch in an upper position (ON): the fan starts itself by switching off the light in the ventilated area and works for the period of time set by the time-lag switches.
II. The switch in a low position (OFF): the fan starts itself by switching on the light in the ventilated area and works for as long as the light is on. After the light is turned off, the fan keeps working for the length of time set by the time-lag switch.
The 5 switch is for adjusting the system sensitivity to the lighting. The upper position (ON) is for dark areas, while the low position (OFF) is for partially lit areas. The system works on condition that there is a significant change in the lighting.
 

E2- timer (pic.5) the fan is activated after the light is switched on (1st version of fan installation) or after pressing the switcher (2nd version of fan installation) look in the (pic.3). After turning off the light or switcher the fan works for the time allocated by the adjustable screw.

Fan models with timer, set the required length of time for the fan to run after the fan is switched off by first ensuring the mains power is isolated, and then with the cover of the fan removed insert a small screwdriver into the aperture marked and slowly rotate clockwise or anti-clockwise to increase or decrease the timer setting from 0 30 minutes.
E3-humidity sensor (pic.5) the fan is activated automatically after receiving expected humidity threshold or switching on the light or switcher connected according to the (pic.3).
The fan works until the switcher or light is on or the humidity above the expected threshold. After turning off the light or switcher and when the humidity is below the expected threshold the fan works for the time allocated by the adjustable screw. The time interval is between 0 - 30 min. The fan has adjustable humidity knob and the humidity threshold could be set up between 30-80%. Please set up all required parameters before use.
The humidity sensor and adjustable knobs are situated in the electronic PCB (pic.5). After connecting the fan with the wiring system ~220-230V , the right knob should be turned on position 0min. and the left one on the low humidity. This settings should activate the fan. The fan works until the humidity threshold is reached by turning the screw very slowly to high humidity position. When the local humidity level is reached the fan should stop after 2 seconds. Then the humidity knob should be turned 10o more to high humidity position. If the fan is not activated it means that the humidity threshold is below 30%. It is possible in winter time when the heaters make the air inside the house very dry. Please leave the humidity knob in position low and set up the timer knob in expected position. The fan should be tested by blowing at the humidity sensor from distance about 10cm.In this moment they should start working.
