An unbeatable duo

Anyone who operates an exhaust air system and an incinerator together in a residential compound knows this: the chimney sweep prescribes electronic exhaust air control!

Exhaust air controls have been the core business of Elektrotechnik Schabus in Stephanskirchen, Bavaria, for many years, and the most popular product of these controls is the radio exhaust air controller FDS 100 with its potential-free contact, which allows the user to switch on the light of the cooker hood regardless of the position of the window, if the hood also offers the possibility to do so. Those who have opted for the top-of-the-range PUR 98 W model from Miele are in luck, for this chic cooker bonnet was not only voted the test winner for recirculation bonnets by Stiftung Warentest in its 03/2021 issue, it also harmonises perfectly with the FDS 100 radio extract air control unit (or the cable extract air control unit) in extract air mode. KDS 110) from Elektrotechnik Schabus. Usually, the electrician looks for the one wire in the electronics of the cooker bonnet that stops the motor in all operating states when the window is closed and connects the two open ends to terminals 1 and 2 of the built-in exhaust air control. With the PUR 98 from Miele, however, there is no need to spend a lot of time trying and searching, even if Miele's installation instructions are silent on the subject, the technical support team at Elektrotechnik Schabus knows the ropes and will give the electrician the right advice. The energy-saving LED lighting on the PUR 98 can be switched on at any time using the convenient touch buttons without having to open the window. However, the FDS 100 is also the only radio exhaust control from Elektrotechnik Schabus that can easily and safely control e.g. the Miele KMDA 7634, which is also a very popular model of the "downdraft extractors" with integrated induction plates, because you also need a potential-free contact for this. By the way, this applies to all trough fans, including those from Bora, Bosch, Neff, and many more. Since the exhaust air motor is integrated in the stove, it is usually supplied with power via a common stove connection panel. Jumpered to one of the phases as delivered, the jumper is removed and in turn connected to terminals 1 and 2 of the exhaust air control. Thus, the exhaust air motor can be started only when the window is open, which also increases the exhaust air performance of these systems, if enough air flows into the kitchen. Everything that the radio control FDS 100 can do, the cable control KDS 110 can do perhaps even better. On the exhaust air control side, it is connected identically, except that a thin cable is laid from the window contact to the control unit. The most important advantages of cable controls are that no batteries are required and that they can be installed directly in the exhaust air system without taking into account possible shielding by metals.
