Hot Water Tank.
I'm lost and would gratefully accept any assistance there maybe out there! I am in the process of fitting two, two port motorised valves at my hot water storage tank. At the hot water tank there is a small copper tube with a single length of steel wire coming from it-this currently links into a thermostatic TRV on the pipework - the position where one of the valves will go. Where do I locate the end of this wire cable, when I fit the motorised valve unit.
As I've already said, thanking you in advance for any information gratefully received.
Regards,
Neil Mac.
