1 Chiller modules X-13650450-02 or greater when installed in a system with a CLD of X-
13650448-01 will call out a diagnostic of (Unknown Diagnostic 905). The machine requires a
CLD of X-136504489-02 or greater.
2 Starter module X-13650453-02 and greater requires Chiller Packet 20.
3 Chiller module X-13650450-01 does not support Packet 20. You need a Chiller module of X-
13650450-02 or greater along with the Starter module X-13650453-02 through 6 or you will
get a diagnostic of starter loss of communication with chiller. Beginning with Starter module
X-13650453-07, the Starter module no longer expects to receive Chiller Packet 20.
Chiller module X-13650450-03 and earlier do not have the bit that the Stepper module looks
for to determine if it should do an inlet vane motor BPI search on startup. These modules will
do a BPI search on each startup.
4 TCI COM3 module X-13650460-01, the TCl packet time to receive the information from
Tracer is 15 seconds. The information is sent out every 10 seconds and you may get repeat
(IFW) informational warning diagnostics filling up the diagnostic logs. TCI COM3 module X-
13650460-02 or greater is required.
5 To read evaporator approach temperature, you need a CLD of X-13650448-04 and later
along with a Chiller module of X-13650450-04 and later.
6 See Trane service bulletins CVHE-SB-90 and 91 for additional module compatibility
information.
