hi all, I have had a viessmann vitodens-100 w 26kw boiler fitted ( type b1hc, b1kc )
serial 7570672

i have picked up a weather comp sensor off fleebay for £15 and want to install it ( V200 outdoor sensor part 7427232 it also has a sticker on the unit that says ntc 10k ) the chap says it will work fins with my boiler but the veissman website says a different one is needed.... both look the same just alot more money to buy direct from veissmann.
can anyone confirm if this will be fine to use?

i also have a hive thermostat megaflow cylinder and the system is closed

any help appreciated!
