If anybody has an old outdoor or weather compensation sensor lying around as spare, PM me, I'll be interested.
I hope it is not against forum rules, I tried to search it but couldn't find if it is forbidden to post queries like these.
I looked it up, Viessmann say that I need this (attached in pic) for my boiler and is listed for 60!
10k NTC are for GBP 30-50 but I am not sure if they are compatible with boiler. I thought I'd ask if someone has parted with a similar boiler and a sensor may be lying around!
