Honeywell L6191B2088U aquastat

Aquastat (thermostat) Honeywell L6191B2088U Dual immersion aquastat 70–140°C with manual reset for high-temperature heating systems and boiler protection. Aquastat Honeywell L6191B2088U (Aquastat) is a specialized dual immersion thermostat for heating systems with high operating temperatures (up to 140°C). The device combines two independent functional modules in one housing: a temperature controller and a safety limit (limit thermostat) with manual reset. Both liquid-filled sensing elements are installed in a common immersion stem and are designed for direct mounting in boilers, water heaters, and other water tanks. The device ensures accurate maintenance of the set high temperature and reliable protection of equipment from overheating. If your heating system operates intermittently, does not reach the required temperature, or frequently shuts down in emergency, the cause may be a faulty standard aquastat.
