Hay,
I'm learning fault finding in CH systems which I'd need help with, please.
I've been given a set example: have got hot water but heating. Measuring the resistance around the room thermostat and the motorised valve together gives a lower total resistance than measuring the individual components. The example is not going into details just shows the expected values (total and individual programmer and 3 port valve) so I worked backwards that it is actually calculating as a parallel wiring not series one. (See picture)
I thought the controls are wired in series normally.
Is parallel wiring an option with these two controls?
Thanks!
