NOTICE
Compressor Damage!
Before connecting power wire to the motor terminals,
with the motor terminal jumpers removed, verify proper
phasing between the drive and motor terminals with an
ohmmeter for all connections. Improper phasing
occurs between the drive and motor terminals can
cause compressor damage.
UC800 Software Installation and
Configuration
Note: The software upgrade process requires that the
UC800 ether have no application code already
installed, or if an application is existing, that the
controller be in the Stop mode and that the compressor
and the pumps have been shut off. TU will enforce this
requirement with pop-up messages at the appropriate
step in the process, but it is best to Stop the chiller
before the software upgrade process begins.
1. Connect the service laptop computer to the target RTHD
UC800 using an A/B type USB cable. Launch Tracer
service tool software in the service computer. If no shortcut
exists, the program can be found in Programs > Trane >
Tracer TU.
