EVO home installation advice help please,

[Billy]

Hi can someone please guide me with the installation of Honeywell Evohome with my combi boiler Viessmann VITODENS100


I am trying to attach a picture of the current wiring but the file is too big to upload, so basically my current thermostat is connected with LR AND L only I don’t see any other cables going to the thermostat. So do I have to do the same with Evohome? If yes then on the Evohome thermostat which socket do I put the LR in AND L in?

Thanks in advance

Hi Billy,

I would suggest contacting Viessmann UK technical for details on how to connect evohome to their boiler.

A copy of their installation guide is here - https://viessmanndirect.co.uk/files//96 ... ctions.PDF
