An unbeatable duo
Anyone who operates an exhaust air system and a combustion plant together in a residential complex will be familiar with this: the chimney sweep requires electronic exhaust air control!
Exhaust air controls have been the core business of Elektrotechnik Schabus in Stephanskirchen, Bavaria, for many years. The most popular product of these controls is the wireless exhaust air control FDS 100 with its potential-free contact, which allows the user to switch on the extractor hood light regardless of the position of the window, if the hood also offers the possibility to do so.
Anyone who has opted for the top model PUR 98 W from Miele is truly lucky, because the stylish extractor hood was not only named test winner of the recirculation hoods by Stiftung Warentest in the 03/2021 issue, it also harmonizes perfectly with the radio exhaust air control FDS 100 (or the cable exhaust air control KDS 110 ) from Elektrotechnik Schabus. Typically, the electrician locates the one wire in the extractor hood's electronics that, when disconnected, shuts off the motor in all operating states with the window closed, and connects the two open ends to terminals 1 and 2 of the built-in exhaust air control. The energy-saving LED lighting of the PUR 98 can thus be switched on at any time using its convenient touch buttons, without having to open the window.
The FDS 100 is also the only wireless exhaust air control from Elektrotechnik Schabus that can easily and safely control the Miele KMDA 7634, another very popular "downward extractor" model with integrated induction hobs, because it also requires a potential-free contact. This applies to all downdraft extractors, including those from Bora, Bosch, Neff, and many more. Because the exhaust air motor is integrated into the cooktop, it is usually powered via a shared cooktop connection panel.
Bridged to one of the phases in the delivery state, the bridge is removed and reconnected to terminals 1 and 2 of the exhaust air control. This allows the exhaust air motor to operate only when the window is open, which also increases the exhaust air performance of these systems when sufficient air flows into the kitchen.
Everything that the FDS 100 radio control can do, the KDS 110 cable control can do, perhaps even better.
On the exhaust air control side, it is connected in the same way, except that a thin cable is run from the window contact to the control unit. The main advantages of cable controls are that no batteries are required and that they can be installed directly into the exhaust air system without considering any possible metal shielding.
