Software Error
1001: Call Trane
Service (beginning
with Rev 29)
All
Reported if a compressor is found to be running without chilled
water flow for three minutes. Previously, this error would be
identified after five minutes.
Software Error
1002: Call Trane
Service (beginning
with Rev 29)
All
Reported if state chart misalignment in stopped or inactive state
occurs.
Software Error

A high level software watchdog has detected a condition in which
there was a continuous 5 minute period of compressor
operation, with neither chilled water flow nor a" contactor
interrupt failure" diagnostic active. The occurrence of this
software error message suggests an internal software state
chart misalignment has occurred. The events that led up to this
failure, if known, should be recorded and transmitted to Trane
