1. Multiple Working Modes - Provides multiple operation modes with flexible wiring options. Choose between single-wire mode (valve stops while the fan continues running) or two-wire mode (valve stops and the fan stops) to suit your system. 2. External Embedded Installation - External embedded installation with a standard 86-type mounting cassette for easy retrofitting and installation. 3. Long Service Life - Electrical life: rated for more than 100,000 cycles at 220V full load. - Mechanical life: the manual switch is rated for more than 60,000 cycles. 4. Stable Performance - Attractive appearance with a comfortable hand feel and reliable operation. - Temperature sensing component uses an accurate metal bellows for stable response. Key attributes - Function: thermostat control for valve and fan with configurable wiring modes. - Compatibility: standard 86-type installation cassette for broad compatibility with existing enclosures. - Size and installation: external embedded design enabling straightforward retrofit and mounting. - Material and sensing: metal bellows temperature sensor for precise and stable sensing. - Performance: high electrical and mechanical lifecycle ratings ensure long-term reliability. Use scenarios - Residential heating control: install in living spaces to modulate a radiator valve and associated fan, maintaining comfortable ambient temperatures with reliable switching. - Ventilation and exhaust systems: suitable for kitchens or bathrooms where valve and fan control must be coordinated to maintain airflow and temperature targets. - Small commercial spaces: offices or shops can leverage the standard 86-type cassette for quick upgrades to achieve stable temperature management and efficient operation.
