Hi, its the one for my boiler – its very small – it’s basically a molex connector with a wire going from 1 pin into another creating the loop. From what I can gather, every boiler comes with one as standard BUT if you fit a programmer, then they timer loop is removed and the programmer is fitted in place.
I see and did not know that, does this loop happen via the connectors on the PCB ?
Seems like timer loop if not connected to Programmer, it is a default for always ON/Active ?
