Not sure what your other device is, but you may also want to disconnect the live and neutral boiler end. Boiler cover forms part of the combustion circuit and needs checking for safety afterwards.

Sorry for the silly question but im totally disconnecting the old receiver? Out of the live and neutral

 

[CBW]

Yes, otherwise it’s getting a power supply for no reason.
