Identifying Systems

[hooner]

Afternoon all.

Is there a way of identifying heating systems (C, M, Y, S etc) without pulling the house apart if the customer doesn't know? Is it just a case of checking the wiring at the programmer/wiring centre or would you need to check the system itself and work it out from system components? (Sorry for asking dumb questions - i'm new to heating and my hands-on training has been sparse to say the least) BTW, we're only doing programmer upgrades at the moment, not fault finding.

Thanks again

Richard

my knowledge is quite limited with this aswell mate, but if you take a pop onto the honeywell website they've got all the wiring diagrams for each plan. you can't go too much wrong if you compare what you've got to each diagram. Its what I've done before and gets me by.

see if programmer is set to gravity or fully pumped. if fully pumped, look for either 2 port valves or 3 port valves
