Installation - Electrical
In many cases, the Trane user-
defined types contain standard
network
variable types (SNVTs) to make
them easy to understand.
User defined types
This appendix includes
❏ User-defined network variable
types
❏ User-defined configuration
property types
These user-defined types have been
created by Trane for use by Trane
controllers.
