ACCESSORIES

Available optional accessories:

Terminal block (standard version, no part index sux). Connect the air exhaust fan with the terminal block as shown in the electrical wiring diagram, see Fig. 2.

The air exhaust fan is started and stopped by a separate on/o switch installed in the power supply line of the building (and not included with the product).

Timer (part index sux“T”). Connect the fan with the timer (a switch-o delay) as shown in the electrical wiring diagram, see Fig. 3.

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 set at 3 min. with the

potentiometer knob rotated counter-clockwise to stop. Turn the potentiometer knob clockwise to set a longer stop delay time accordingly. The maximum stop delay

time setting is 30 min. The stop delay time is adjusted in innite increments. The stop delay time is counted down from the moment when the signal at the“SL” terminal

disappears caused by switching o the lighting or the on/o switch to which the appliance is connected. Depending on the setting of the “DELAY” slider on the

controller, the fan will start operating when voltage is detected on the “SL” terminal or after 2 minutes after voltage is detected.

Humidity sensor (part name sux “H”). Models equipped with humidity sensor (hygrostat) and timer should be connected according to the connection diagram

in Fig. 3. or Fig. 4.

The air humidity sensor detects humidity between 40% (“HIGRO” potentiometer turned maximum to the left) and 90% (“HIGRO”potentiometer turned maximum to the

right) of relative humidity. The system is additionally equipped with a timer. The operation of the fan depends on the power supply connection method. If connected as

shown in Fig.4, the fan will start automatically when the air humidity level exceeds the set value of the humidity sensor. Next, the fan will switch o when the air

humidity level is reduced below the set value, plus the switch-o delay time set with the timer elapses. Switch-o delay time is regulated by the “CZAS/TIME”

potentiometer in the range of 3-30min (the minimum switch-o delay time is obtained by turning the potentiometer maximum to the left).

If connected as shown in Fig. 3, the fan can also be started with its standard light sensor or operating the separate on/o switch. Depending on the setting of the

“DELAY” slider on the controller, the fan will start operating when voltage is detected on the“SL” terminal or after 2 minutes after voltage is detected. After a signal loss

at the “SL” terminal due to switching o the light or the on/o switch, the air exhaust fan will stop after the stop delay time set with the potentiometer if the humidity

level in the room is below the level preset on the potentiometer. The humidity detection system is the master system.

NOTE: 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 fan shall only be installed, connected to electrical mains and commissioned

for use by qualiﬁed personnel in accordance with applicable laws!
