How to Fix / Troubleshooting
Safety first: Immediately switch off power at the fused spur or consumer unit. Do not continue using a thermostat that smells of burning or is excessively hot.
- Do not open casing: Leave the thermostat casing closed to avoid exposure to damaged components.
- Check wiring: After power is off, verify that the thermostat is not wired directly to 230V on terminals intended for low voltage. Correct any miswiring before restoring power.
- Do not reuse faulty unit: Replace the thermostat with a new Vokera smart thermostat. Do not attempt to repair a unit that has overheated.
- Inspect surrounding area: Ensure no damage has occurred to the wall or wiring insulation.
