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?

From what I see from picture these Eliwell ECH420 are actually rebadged Microtech Energy 420.

E42 is faulty probe ST4
