Exhaust air systems such as bathroom fans create a negative pressure in the room if not enough air can flow in. As soon as a combustion appliance (e.g. gas boiler) is located in the same room, dangerous exhaust gases can be extracted from it and spread throughout the room.
By using the FGS 170 wireless exhaust air control, an exhaust air system can only be used if, for example, this gas boiler is not ignited.
A potential-free contact (normally closed or normally open) must be available on the gas boiler, which is queried by the FGS 170 and transmits the operating status of the gas boiler to the receiver.
Additional FGS 170-E receivers (article 300701, page 27) for other fans are only available from our online store (please quote the serial number of the existing set) and not from retailers, as we produce additional devices especially for you.
Performance features
- Transmitter for 230 V operation (without batteries)
- Radio link monitoring
- Relay contact receiver 5 A changeover contact (potential-free)
My gas boiler only outputs 230 volts when ignited.
This happens more often, but it is better than no signal at all. Ask your electrician to bring a 230 V relay to the installation so that he can establish a potential-free contact and thus control the FGS 170 transmitter.
The transmitter is connected with a cable to the potential-free contact (NC contact) of the gas boiler. As soon as combustion starts and the contact opens, a receiver is activated via radio, which switches off the exhaust air system (e.g. bathroom fan). The receiver can be surface-mounted or flush-mounted in a distribution box, switch or socket with a minimum diameter of 60 mm. The fixing lugs on the side of the receiver can be broken off if required *Make sure that the radio waves are not shielded (wall, metal, etc.), the range depends on the installation.

I think the Schabus system is ingenious. Unfortunately, the radio receiver I bought in 2018 is already defective. I hope this one is more durable!
