preferable. The factory setting is 75°C.
Reset button
Located on the upper part of the TS2 thermostat, this button will release and cut all power to the heating
element if the internal temperature in the water heater rises above 98°C. If this occurs, the function of the
thermostat must be checked by authorized personnel before the reset button is pressed.
Internal wiring
All internal wiring is factory fitted. 2.5 mm² wires are standard. The RI SD is also factory fitted with a standard
external power cable, complete with plug for grounded sockets. Lenght 3 m.
Heating element
RG 5/4”. The element is resistant to up to 250 mg. Cl/litre.
An RG 5/4” - 4,5 kW - 230V 2-phase element is also available as an option if shorter heat-up time is required.
