Trane CVHE Installation Instructions Manual page 43

There has been a tendency with installers to change this
setting to the "North America" setting. The preset
parameters are "Motor Power in KW based." Changing
[0-03 Regional Settings] to "North America" will change
the drive to "Motor Power in HP based." This will reset
all of the presets to the default settings. If this
occurs all of the presets must be reprogrammed.

Refer to Table 19 for a list of items that are programmed in
the drive at the factory for use with Trane® chillers. In the

Always confirm before actual drive start up that this is so
and correct any one of the parameter settings as
necessary.
