Thermostat ARISTON (30L) 691598

ARISTON 691598 is an original contact-type thermostat designed for selected ARISTON 30 L electric water heaters. The thermostat monitors water temperature and automatically controls switching of the heating element, maintaining the temperature selected by the user. The manufacturer's spare-part code is 691598, and the EAN is 5411692111038.

The thermostat is a mechanical temperature-control device that detects temperature through contact between its sensing component and the water-heater structure. It combines normal operating-temperature control with a safety function designed to interrupt the heating circuit in the event of an abnormal temperature condition. The component is identified as a TIS T-85 type thermostat with a rated current of 15 A and voltage up to 250 V.

The adjustable operating-temperature range is approximately 40–80 °C. This allows the water heater to maintain the selected water temperature automatically by switching the heating element on and off as required.

ARISTON 691598 is principally intended for smaller-capacity ARISTON electric water heaters, including 30 L models. Documented compatibility includes ARISTON EP 30 O, VID 30 R, TI 30 ORES and corresponding small-capacity SG and TI-SHAPE models. In the ARISTON VID 30 R spare-parts diagram, 691598 is directly identified as the thermostat.

The spare part is intended to replace a damaged or worn thermostat. A correctly functioning thermostat is an essential part of the water heater's control and safety system because it is responsible for maintaining the selected temperature and disconnecting the heating element when required.
