I have seen it listed as a replacement for the HM505 but was not sure whether it is the same for the HM525. RE: Microm - HM520/HM525

5 RepliesDoes anyone know if the temperature sensor in a Microm 505/520/525 (p/n 330320) is a PT1000?
[The manual for the 550 says that sensor is a PT1000, but it's a different p/n.] RE: Microm - HM520/HM525

I have a HM520, that had a refrigerant leak. Had unit repaired and refilled, but now I am getting a E01. I don't have a good service manual, but what I have says it is a power failure. If anyone has a copy of the manual or can give me a hand. Let me know
Thanks
