## Long description

DEDIETRICH AD199 is a circulation sensor engineered for heating and hot-water circuits that incorporate a mixer. Supplied as a compact sensing unit, the device monitors circulation and flow-related parameters to provide input for system controllers and safety functions. It is suitable for integration into boilers, hot-water distribution loops and hydronic systems where accurate detection of fluid movement in a mixed circuit is required.
Advantages
The circulation sensor offers precise detection of flow or circulation status in systems with a mixer, supporting reliable automation and protection of the heating circuit. Its design is compatible with common hydronic installations and facilitates straightforward integration with control electronics. The sensor contributes to improved system stability by enabling timely responses to changes in circulation conditions.
Suitable for
Boiler systems with mixer-controlled hot-water circuits
Hydronic heating distribution loops requiring circulation monitoring
OEM or service replacement in compatible heating appliances
Key specifications
Function: circulation/flow detection for mixed circuits
Application: heating and domestic hot-water systems with mixer
Compatibility: intended for integration with boiler control systems and hydronic components
Form factor: compact sensor unit suitable for in-line or circuit installation
Signal output: provides operational feedback to system controllers (electrical interface depends on system)
How to use
Install the circulation sensor in the circuit branch downstream or upstream of the mixer according to the system manufacturer’s instructions and wiring diagram. Ensure the sensor housing and connection points are compatible with the pipework and that sealing or mounting accessories are used to prevent leaks. Connect the sensor output to the boiler or controller input dedicated to circulation monitoring, verify electrical and hydraulic connections, then restore system pressure and check for correct detection during pump operation.
Usage recommendations
