Hi, I have 2no. 3rd generation thermostats and 1 heat link. Over the weekend I had my boiler services and one of the thermostats lost the link to the heat link. I pressed the heat link till flashed blue and relinked my thermostat to the heat link after a H71 code. This reconnected and I thought all was fine. I then realised the second thermostat had then lost connectivity. I followed the same step and reconnected but doing this then removed the other thermostat. Please can someone advise how I re link both thermostats at the same time please?
