Hello there! I'm sorry to hear about this, but I'll be more than happy to assist. Could you please answer the following questions:

2. How long has your thermostat been installed for?
3. What colour is the Heat Link LED?
4. What is showing on the Nest thermostat display?
5. Have you had any power cuts recently?
6. Have you had any work done on your electrical or heating systems recently?
7. How many zones are present in the setup?

Thanks in advance, Oana.
