Hi All, wondered if someone can advice me.
Boiler and Honeywell themostat were fitted last year.
The themostat was switching on and off, we replaced the battery but wasn't still working properly.
Now ordered Honeywell Home T3R Programmable Wireless Thermostat (Y3H710RF) how do we connect it to the boiler. I have added picture of the old themostat. The numbers of the themostat aren't exactly the same. Not sure if the previous one was wired and new one is wireless.
