What it is
The Ariston 65112045 is a manual reset thermostat used on Ariston Kairos MACC unvented cylinders. It monitors cylinder temperature and cuts the heat source if the set point is exceeded, requiring a manual reset before the appliance will run again. It forms part of the cylinder's thermal safety control rather than the primary temperature regulation.
Signs this part needs replacing
- The cylinder stops heating and the reset button will not latch or hold.
- The thermostat trips repeatedly, requiring reset after every heating cycle.
- No hot water despite the cylinder controls calling for heat.
- The reset trips at temperatures well below the normal cylinder set point.
- Visible damage, scorching or a loose or corroded connection at the thermostat terminals.
Before you order
- Confirm the cylinder model against the fit list above, including any CODE number shown on the data plate.
- Check the existing thermostat's part number and reset type before removing it.
- Isolate the electrical supply to the cylinder and verify the fault is with the thermostat rather than the cylinder controls or heating source.
- Confirm whether a manual reset device is the correct type for your installation.
