Background Illumination; Technical Data - Bresser VentAir Manuel D'instructions

1. Press and hold the touch control CH/
the data will normally be received within 3 minutes.
2. If the first step does not yield a desirable solution, please remove the batteries and re-install them
(hardware reset).
At the same time, please make sure the following:
1. The main unit as well as the sensor should be at least 5 to 6 feet (1.5 to 2 meters) away from any
interfering sources, such as computer monitors or TV sets.
2. The main unit should not stand close to metal window frames.
3. Please do not use other electrical products, such as headphones or speakers, operating on the same
signal frequency (433 MHz).
4. Electrical devices operating on the same signal frequency may also cause interference. This can include
devices used in the neighborhood as well.
Main unit channel setting
1. The main unit can be connected with a maximum of up to 3 transmitters.
2. Press the touch control CH/
display the information of the corresponding transmitter. When the symbol
channel information the automatic display rotation is activated. The display changes between the
information of the connected remote sensors every 10 seconds.
NOTE!
The function to change the channels by pressing the CH/
outdoor sensor is connected with the main unit. Otherwise this function is disabled.

Background illumination

Press LIGHT button (5) to to turn on the background. It will be turned off automatically after approx. 5
seconds.
Sensor function
1. Move the CH switch (24) to the position (1-3) that corresponds with the channel which will be used for
transmission (select channel 1 if only one outdoor sensor is connected). If you would like to connect
more than one outdoor sensor with the main unit, different channels need to be selected for each
sensor.
2. Once the weather station receives radio signals from the sensors, the alternating temperature values of
the different channels will be updated on the weather station every 1-2 minutes.
TROUBLESHOOTING
Signal disconnection
If the display of the outdoor temperature goes blank without obvious reasons, please check the following:
1. The outdoor sensor is still in place.
2. The batteries of both the sensor and the main unit are not empty. Replace batteries with new ones if
necessary.
NOTE!
When the temperature drops below freezing point, the batteries of the outdoor sensor can also freeze
and their voltage and lifetime are reduced.
3. Both devices are positioned within the reception area and the reception area is free of sources of
interference and obstacles. If necessary, reduce the distance between the devices.
Transmission collision
Signals from other household devices, such as door bells, home security systems and entry controls, may
interfere with those of this product and cause temporarily reception failure. This is normal and does not
affect the general performance of the product. The transmission and reception of temperature readings
will resume once the interference recedes.
