2.15 Pumpdown – General
CAUTION
System pressure below atmospheric pressure! Compressor damage!
Never operate the system below atmospheric pressure. There is a risk of
malfunction of the controller in deep vacuum operation which can cause
compressor damage.
Pumpdown functionality is not provided by the XCM25D controller for condensing unit models OMTE
or OLTE covered in these guidelines.
2.16 Reset to factory settings – Emerson "Hot Key"

2.16.1 How to save factory settings or user settings

There is no way to reset the XCM25D controller to factory settings other than with additional
equipment. Emerson recommends using the Emerson "Hot Key" (not part of the standard delivery)
to save the factory settings at initial power up. The same hot key can also be used to save user
settings.
By means of a special programming software (Emerson Wizmate) and corresponding hardware
(Emerson Prog-Tool), the user can:
▪
preprogram hot keys
▪
copy hot keys
▪
change parameter levels
▪
compare parameter lists
