We have two nest thermostats installed over a month ago and i am not sure the issue was after or before the installation of nest thermostat.
We have two zones of heating installed in our house.One is for ground floor zone to contro kitchen and living area heating system (with radiators) and second one is 1st floor zone to control bedrooms heating system (with radiators).
Recently i found that the one of the bedroom raditor heating is controlled with ground floor thermostat zone instead of first floor theromostat.I am confused where the problem is is it the issue with nest installation engineer did or my new property initial plumber did the wrong connections.
Please suggest me whom i need to turn for help?My nest engineers says it is issue with plumbing work but my builder says it is nest engineer who did the wrong connections.
Thanks for your help
