Honeywell L6191B2047U aquastat

Aquastat Honeywell L6191B2047U — dual immersion thermostat (regulator + high limit with manual reset) for boilers. Ensure precise regulation and maximum overheat protection in your heating system with the dual aquastat Honeywell L6191B2047U. This professional device combines two independent thermostats with a common immersion sensor in one housing: one operates as the main temperature regulator, the second as a high-temperature limit (high limit) with manual reset. The model is ideal for gas, solid fuel and combination boilers, water heaters and hydraulic heating systems where stable control and enhanced safety are required. Key advantages: Dual design — one device performs two important functions: maintaining the set temperature and emergency overheat protection. Regulator: range 95–140 °C with adjustable differential 4–10 °C — convenient external knob for quick adjustment. High Limit: 70–140 °C with manual reset — triggers when the maximum temperature is exceeded and locks the system until manual intervention, preventing accidents. SPDT contacts on both modules — universal connection for controlling the burner, circulation pump and other elements. Fast response thanks to liquid-filled sensing element in a common immersion well (well ordered separately). High reliability — switching capacity 10(2.5) A at 250 V, ambient temperature 0…70 °C. Main characteristics: Type: dual immersion aquastat Regulator: 95…140 °C, differential 4…10 °C (adjustable), SPDT, external knob High limit: 70…140 °C, manual reset, SPDT, internal adjustment Mounting: direct immersion in common well Housing: compact, with protective cover and
