That's because the above email address is not the one you registered with.
What happened to the tony at NH3 etc?
If you are going to register a email address at least make it one that works.

I did get a simplified wiring diagram for this chiller from Carrier but it ain't helping
I need to figure out the circuitry relating to the pumps, pump failure , flow switch etc.
I would appreciate any help you can provide
best wishes

Hi Tony.
Sorry for the delay, I have been working away in Cornwall. Just got back tonight just before the summer rush. (It's the weekend that all the schools break up for summer holiday) ( for the non uk readers benifit!).

Anyway for your info and anyone else that may find it useful?

Mucho Thanks Grizzly
Is there much work in Cornwall ?
(wife says she would like to move there)
I do already have this from carrier site - but (as an old fart) who started working life as an electrician I was looking for a "proper" schematic.
I find it difficult to interpret the info in this simplified diagram - guess I need to get brain in gear and view components list, side-by-side with the drawing.
I have got 2 of the 3 chillers running now - 2 fried evap circ pumps cos someone had connected both pumps to run in same direction giving flow probs etc.
Other chiller waiting on fan and pump rewinds back before further investigation.
regards
Tony
