Again thanks
why don't vaillant put a notice in the uk manual saying its not supplied as standard.
Has anybody obtained and fitted a vrc9535 in uk?
Anyway I'll wire it with 3 core for future upgrade
Cheers
Thanks simond,
Thats right the two wire is just the basic temp sensor and the three wire has the temp sensor and radio clock reciever built in, so the vrc430 will automatically change between summer and winter times. If I'm wrong someone will tell me. Anyway it's back to the supplier as it's...
Thanks Gas4you,
The installation Manual lists two sensors the vrc 693 which i have in box and the vrc9535 which i don't have. Should I have both sensors? the manual does not say the vrc9535 is an extra and cant find either of sensors for sale as indivual parts
