Honeywell L6188A2002U aquastat

Aquastat (thermostat) Honeywell L6188A2002U Immersion liquid-filled thermostat 25–95°C for precise temperature control in heating and DHW systems Aquastat Honeywell L6188A2002U is a reliable immersion thermostat (SPDT) with a liquid-filled sensor, designed for regulating and limiting water temperature in heating and domestic hot water systems. The highly sensitive liquid-filled sensing element 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.
