Honeywell L6189A2043U aquastat

Aquastat (thermostat) Honeywell L6189A2043U Surface-mount liquid-filled thermostat 40–110°C with remote capillary 1.5 m for protection and regulation of heating and DHW systems. The Honeywell L6189A2043U Aquastat is a reliable surface-mount thermostat with a liquid-filled sensor, designed for regulating and limiting the maximum water temperature in heating and hot water systems. Unlike immersion models, this aquastat is mounted on the surface and connected to the system via a capillary tube 1.5 m long, allowing convenient placement on the water heater body or pipeline. The highly sensitive liquid-filled sensor provides a fast response to changes in coolant temperature. If your boiler or water heater no longer shuts off when the set temperature is reached, does not heat, or operates intermittently, the cause is often a faulty built-in aquastat.
