Dunham Bush Chiller Fault Codes

[iceman007]

Does anyone have any fault codes for Dunham Bush Chillers. Its a bit of an old one (1996) No ongoing maintenance and a bit of a mess. Two Refcomp recips and total capacity I think 415kW.

Three codes show on the history 10, 19 and 26. No OEM manuals anywhere either, so relying on some outside help.

Thanks

Thanks for the link, but this chiller will have the old MP2000 control panel and gives nothing other than 2 digit codes for errors.
Cheers

Looks like I might have to try and contact Dunham Bush. But Thanks for the attempts anyway. Very much appreciated.

No problem!

Perhaps I can help more, but I can't remember what the MP2000 looks like in the front (display)! Perhaps than I can find the correct manual (paper) here at home!

If your unit does have a Mp2000 controller, then go to the Digital menu. Enter, and then scroll down until the number corresponds with your alarm code. i.e digital 10 may say something like Oil Pressure Switch circuit 1. This will tell you a oil failure problem on that circuit. Hope that is clear..
