Radio exhaust air control FDS 100 DIBt

The exhaust air system can only be used when the window is open and the necessary supply air can flow into the room. A transmitter on the window sash monitors whether the window is open or closed and transmits this information by radio to the receiver. The latter releases the power supply only when the window is tilted or open.

Lighting independent of the window position: The one line that safely switches off the fan motor in all operating states is disconnected and reconnected to the normally open contact (terminals 1 and 2) of the FDS 100.

Control of a control contact: Some manufacturers of exhaust air systems provide a contact that only controls the fan motor, often fitted with a wire jumper when delivered. This jumper is released and switched with the normally open contact of the FDS 100.

Second window (OR): At least one window must be open for the exhaust air system to be switched on. To do this, connect the FDS 100 SET to the additional transmitter FDS 098 or FDS 098 L (note dimensions!) for the second window.

Second window (AND): Two windows must be open at the same time so that the exhaust air system can be switched on. This requires two independent FDS 100 SETs with different coding. The receiver relays must be connected in series.

Second receiver An additional receiver (installation) can be added to the existing FDS 100 set. FDS 199 or intermediate plug FDS 299) can be controlled. As soon as the window is opened, both receivers enable the respective exhaust air system.

FDS 100 combined with flue gas temperature monitor: As soon as the flue gas temperature in the flue gas pipe exceeds 40°C, the window must be opened in the process:

• Lighting of the extractor bonnet also works when the window is closed, if only the motor supply line is switched
• potential-free contact for switching motors or control contacts
• suitable e.g. for BORA Professional Home In, Miele PUR 98, Miele KMDA7774

Scope of delivery

• 1x receiver
• 1x radio magnetic switch (transmitter and magnet)
• 1x battery CR2032
• 4x spacer plates for magnet
• Mounting material
• Operating instructions

Color telegrey, transmitter housing also available on request in various RAL colors available against surcharge

Our device performs an automatic RESET cyclically, after which the window must be opened once for renewed start-up (and closed beforehand if necessary).
With a "normal use" of 1-2 hours / day and optimal radio connection (no stainless steel or other shielding materials, ideally with visual contact), a battery life of up to 2 years can be expected with a fresh brand battery.

Connection examples

	Connection example 1 When the window is closed, the receiver switches off the current to the fan motor of the extractor hood or ventilation system. The receiver can be surface-mounted or flush-mounted in a distribution box, switch box or socket with a minimum diameter of 60 mm. The side mounting tabs on the receiver can be broken away if necessary. Installation in the cooker hood itself should be avoided in the interest of a good radio connection.
	Connection example 2 For older cooker hoods with mechanical fan speed control, the receiver is interposed in the fan motor supply line so that the lighting of the cooker hood functions independently of the window position.
	Connection example 3 Some fume hood manufacturers offer external connection modules for separate control of the fan motor, e.g. BORA Professional Home In, Miele KMDA7774, and many more. This can be realized with the potential-free relay contact of the FDS 100 receiver. With connection to a control contact, the FDS 100 also becomes BLDC-capable.
	Connection example 4 Bosch, Neff, etc. trough fans often have the stove connection panel with its own connection for the fan motor. The jumper must be removed, a conductor is branched off from one of the L connections and connected to the L1 input of the stove connection panel via terminals 1 and 2 of the FDS 100.

Caution. Metals shield radio * Obstacles, especially metals, sometimes reduce the range considerably compared to free space. The actual range always depends on the respective installation. In case of frequent dropouts during operation, despite fresh battery, a bad radio link is often to blame. The distance between transmitter and receiver hardly plays a role. Keep the receiver at least 20 cm away from the nearest metal surface. Thick glass plates, ceramic hobs, kitchen cabinets with pots and pans, as well as walls and ceilings also shield the radio waves perfectly and interfere with reliable operation. For a good connection, align the receiver during installation so that its LED "looks" in the direction of the transmitter.
