What it is
The Ferroli 39805640 is a spring thermostat rated at 88°C for central heating. It is used in Ferroli gas boilers to control the central heating temperature circuit. The thermostat forms part of the boiler's central heating temperature regulation.
Signs this part needs replacing
- The central heating circuit does not reach or hold its expected temperature.
- The boiler cycles on and off more frequently than normal.
- Heating demand is not controlled correctly, with the boiler running when it should be off or failing to fire when heat is called for.
- The thermostat shows mechanical wear, corrosion or a weak spring action.
- Overheat or lockout faults appear that point to the central heating thermostat circuit.
Before you order
- Confirm the boiler model and GC number against the fitment list above.
- Check the existing thermostat is marked 39805640 or matches the 88°C central heating specification.
- Verify the appliance is a Ferroli gas boiler using a spring thermostat for central heating.
- Check that the thermostat temperature rating matches the removed part before fitting.
