Ok then, that'll work. Now you know how to wire big machines!

I used to build/maintain coating machines such as this (the largest we ran was bigger than most houses):


All you gotta do is reproduce your diagram (in various iterations) about 10,000 times and you can make one of these babys run!

So Lux (and Matt) --- I got your seal of approval on this? Should I fuse anything anywhere? or is that not needed?

Looks good. Make sure that the transformer and relay are UL listed (not that it helps a lot, but some). You could put a fuse in the 24V line, rated between the transformer output current and the relay coil current requirement. Other than that, the fuse on the 110V line that you have should be sufficient.

Will do! And Thanks!

Might not be a bad idea. All the HVAC equipment I've ever dealt with has been is fuse protected at the thermostat control transformer.

Ok! Got all my goodies from Allied (thanks for the tip! They're a great outfit!!)

I have a question:

I got this relay:

http://www.azettler.com/pdfs/az2280.pdf

(the AZ2280-1A-24A)

I just want to make 100% sure... I can keep 24VAC (Which is actually 27.0VAC out of the transformer) on the two coil terminals for as long as needed (say, for example, DAYS)... Tech support at Zettler is "out of the office" -- so I thought I'd ask here...

Thanks,

Pete

Seems the answer is "Yes" -- but I thought I'd run it past you guys too...

Seems to work like a charm!
