Hello All,

wondering if anyone has any manuals or info on this controller please chiller.jpg

All it says EXTK on the front and the closest i can find online is a Eliwell XT PRO, if anyone has a manual for it or can help me with fault code that appears on compressor 2 (which we have currently taken off the system)

The fault code is showing OR Sensor Fault Compressor 2, but having no info on the system what so ever makes it difficult knowing what OR sensor is, i did wonder if it was Oil Regulator? but then why would it only start having this fault as of friday when we disconnected the comp 3 weeks ago?

Thanks all
