- Transmitter for 230 V operation (without batteries)
- Radio link monitoring
- Relay contact receiver 5 A changeover contact (potential-free)
Exhaust air systems such as bathroom ventilators create a negative pressure in the room if not enough air can flow in. As soon as a combustion site (e.g. gas boiler) is located in the same room compound, dangerous exhaust gases can be extracted from it and spread in the room. By using the radio exhaust air control FGS 170, an exhaust air system can only be used if, for example, this gas boiler is not ignited. On the part of the gas boiler there must be a potential-free contact (opener or closer), which is interrogated by the FGS 170 and transmits the operating status of the gas boiler to the receiver.
In addition to the existing FGS 170 set, a further receiver with the same factoryFGS 170-E of the same factory coding (0 to 9) can be used. When ordering, please specify the serial number of your existing set.
My gas boiler only outputs 230 volts when ignited.
This also occurs frequently, but is better than no message at all. Ask your electrician to bring a 230 V relay to the installation, then he can use it to make a potential-free contact and thus control the FGS 170 transmitter.
