invensys ech 420 controller
I've been working on 4 York Chillers today YCLC 302 ELN and they each have an Invensys ECH420 controller.
3 of the controllers were lit up with E100 and the other one was showing a fault code something like E142.
I've looked for a manual online showing how to use the controller and what the codes mean but i can't find the correct one.
Can anyone help?
