Hello,
I have a friend who has a Alpha CB50 Boiler running off a Alpha thermostat. He wants to install a Nest thermostat.
Do any of you nice people out there have a wiring diagram we can work off?
Thanks in advance
Tom
Here are the thermostat connections, I am unable to remove the cable between the old programmer and the thermostat. I presume if i connect both the 'Live' and 'Switched Live' wires together behind the old thermostat using a chock block this will be OK ?
Thanks very much for that Jackthom. I have taken the old connection plate off the wall and it looks like a rats nest of wires behind there. Do you know of anyone in the Wallsend area who can install it for me?
Thanks again
Tom
Hi,
I have just moved into a new house and it has a British Gas UP1L controller and thermostat controlling the heating and hot water. I have a new 3rd Generation NEST controller and thermostat to install and I cannot find a wiring diagram for the UP1L.
N and L are self explanatory.
I think 1...
