Hint: When mounting the probe, make sure that it is not bent or damaged.
Functional description:
By using the FTW 519 radio temperature monitor on the free stovepipe, an exhaust air system can only be used when the stove or combustion site is not running and is cold or a window has been opened. A transmitter in the radio temperature monitor monitors whether the stove is burning or off and transmits this information by radio to the receiver. The receiver releases the power to the connected device only when the stove is off. If the stove is on, the exhaust air system can continue to operate with an open window. For optimal radio transmission, the FTW transmitter is equipped with an external antenna. The FTW 519 is mounted by means of a flange that is screwed to the side of the stove pipe. The maximum permissible temperature at the transmitter of the FTW is 65°C.
In this case, the FTW must be freely surrounded by room air and is not mounted above heat dissipating parts. A free stovepipe is always visible in the room and is neither covered nor walled in. A typical example is a Swedish stove standing in the room, whose stove pipe is only connected to the chimney after at least 1 meter.
Additional transmitter for second window
In order to have a choice between two windows (OR function), it is possible to use an additional transmitter FDS 098 of the same code, which is programmed at the factory.
Second recipientz
to the existing set, an additional receiver (installation FDS 199 or intermediate plug FDS 299) can be controlled. As soon as the furnace is cold or a window has been opened, both receivers enable the respective connected device. When ordering additional devices, always specify the serial number of your existing receiver.
Operating note
For technical reasons, the operation of a radio thermosensor is only permitted with one existing furnace. If two or more furnaces are to be equipped with the FTW, safe operation is not sufficiently guaranteed. In this case, please contact us so that we can find an individual solution for you

So far it works perfectly. For us it was important not to always have to open the window when the fireplace is not in use.
