Hi, I have a heat only boiler for central heating only, not installed or commissioned yet. I am trying to understand electrics; e.g I got a wiring center (pre wired) for Y plan system. At this stage I only want to control Central heating through programmer and thermostat (no hot water).
The programmer is drayton LP822 (dual channel) and and old dial type thermostat. I will be using the one channel for central heating only.
Its a very basic system for most of you but I haven't done it before so I just want to make sure that I don't burn or damage any components or boiler's PCB.
Attached are two pictures of boiler PCB with a capacitor connected to boiler PCB, I am not sure what is the purpose of the capacitor and does it needs to be wired in wiring center? In the wiring center there was a black wire which wasn't connected to any terminal but taped and tucked separately inside, could it be that is coming from this capacitor? I have made connections from boiler's N,L,E to the wiring center, have also wired the external pump to the wiring center under relevant terminals Terminal 12 and 13 marked as boiler and pump terminal respectively. Boiler documentation says no pump over run required.(see attached)
I have run a two core wire (low voltage) from wiring center to Lounge where I want to install programmer and thermostat. I believe this cable will make call for heat via thermostat or programmer, and power (N,L,E connections) can be taken from home wiring? Correct or do I have to run N,L,E connections all the way from wiring center to the programmer?
Thanks for any help or guidance in advance.
