Discuss Nest thermostat e installation in the Central Heating Systems area at ElectriciansForums.net
Thanks for the reply I'm having trouble identifying the correct wires using the nest app instructions. I was hoping someone had done a similar swap and could help me identify the correct two wires from the picture.once again any help would be appreciated.
nest thermostat requires 12v dc.
take brown and blue and connect to t1 and t2 on nest receiver
if you have a combi boiler it isnt too hard but if you have a system boiler then it is a bit more complicated.
see manual aswell.
Nest thermostat e does not require a 12v supply and does not have a receiver.
Following your advice to connect brown and blue will result in a short circuit and damage to the nest thermostat e
So L and B wires are the ones you need and a block on the blue wireI opened up the old reciver and Blue connected to N (not needed for thermostat e) brown connected to L. Then a small piece of black wire looped going from L (next to brown over to A) then finally a grey wire connected to B.
