Temperature monitor FDS 200

This comfort package without DIBt approval includes a classic FDS 200 extract air control set consisting of a radio window switch with intermediate plug receiver and an FTX flue gas temperature monitor with remote transmitter for shorter or covered but always freely accessible stovepipes. This means that for very rarely used stoves, a window does not always have to be opened every time the exhaust air system is used. DESCRIPTION Functional description: The radio temperature monitor is used to monitor the exhaust gas temperature in the flue pipe of heat generating systems. The heat acts on a precision microswitch, which above the fixed limit temperature switches off the transmitter for the release messages and thus does not release the exhaust air system. After the temperature at the sensor is lowered by approx. 15K below the fixed limit value of 40°C, the microswitch switches back and the transmitter sends release signals again. The window transmitter included in the set releases the exhaust air system when the window is open, if the furnace is burning and no release signals are sent from the FTX transmitter. Closing the window will cause a short interruption even though the furnace is cold, until the next release is sent from the FTX. This serves an extended safety. Mechanical damage to the sensor leads to a lowering of the switching point until the FTX no longer releases despite a cold furnace, therefore the system is intrinsically safe! Use and mounting of the FTX The FTX 519 is mounted on a free piece of the flue gas pipe with a minimum diameter of 120mm, which is freely accessible at all times. The pipe can be located behind a maintenance flap,
