The Giacomini K373Y021 thermostat is designed for automatic regulation of water temperature in heating systems, making it ideal for use in heat stations and boiler rooms. The device features a sensitive immersed bulb that is installed directly onto the heating pipe, ensuring precise temperature control from 0 to 90°C with adjustment via a front dial.

When the set temperature is reached, the thermostat cuts off the heat flow, and automatically restarts when the temperature drops below the desired level. It has a metal housing with a 1/2” NPT-M connection and a maximum factory pressure of 10 bar, as well as resistance to temperatures up to 125°C in the bulb. This model complies with EN 60730-1 and EN 60730-2-9 standards, and bears the CE mark and INAIL approval according to Italian regulations.
