What it is
The Ariston 925275 is a thermostat supplied complete with its wiring assembly. It is fitted to the Ariston Comfort and STI models listed below, including indirect and Protech versions, where it controls the stored water temperature by switching the heat source. The assembly is supplied as a complete unit so the thermostat and its wiring can be renewed together.
Signs this part needs replacing
- Stored water runs consistently hotter or cooler than the temperature set on the control
- The appliance fails to reach temperature, or adjusting the thermostat has no effect
- The heat source runs continuously or cuts out earlier than expected
- Intermittent hot water with no other obvious cause
- Visible damage, discolouration or loose wiring at the thermostat or its connections
Before you order
- Confirm your model and serial number against the Fits list — several models are covered by serial number ranges
- Check the existing thermostat and wiring assembly to confirm the terminal layout matches
- Isolate the electrical supply before removing or fitting the thermostat
