Character Sets
Indicates support for multiple characters sets, but does not
imply that all character sets are supported simultaneously.
Maximum supported string length is 64 bytes (any
character set).
Object Data Points and Diagnostic Data Points
with Corresponding Chiller Models
For quick reference, the following tables are listed two
different ways. Table 99 through Table 104 are listed by
input/output type and sorted by object identifier.These
tables provide the user with the units type for each object
type. Table 105 is sorted by object name and provides a
complete list of object names, types, values/ranges, and
descriptions. Not all points are available to the user.The
available data points are defined during self-configuration
and are dependent on the type of equipment
