Hi Cristian,
Thanks for your reply, although due to the delay in receiving any response and with no luck with our local merchant in upholding the two year warranty, we had no option but to purchase another control system at our expense (definitely decided against a Nest this time)
However, in answer to your questions, which I hope may help:
No lights whatsoever, the Heatlink was completely dead.
How long has your thermostat been installed for? - a week over 1 year when we had the boiler replaced
Did the issue happen during the installation? - No, it happened overnight. The heating was working in the evening but not in the morning
Is there any error on the Nest thermostat display? The thermostat said that it couldn't connect to the heatlink
Have you had any power cuts recently? - No
Have you had any work done on your electrical or heating systems recently? - No
If yes, was the power properly restored at the fuse board after work was done? - All power has been maintained
How many zones ( thermostats ) are present in the setup? - just one, its was operating a combi boiler
My regards
Steve
