Diagnostics

Automatic Reset by the Controller

Manual Output Test

There are four ways in which diagnostics are reset:

1.Automatic reset by the controller

2.By initiating a manual output test at the controller

3.By cycling power to the controller

4.Through Rover™, Trane’s service tool

The controller includes an automatic diagnostic reset function which attempts to automatically restore the unit when a low temperature diagnostic occurs.

Note: The controller implements the automatic diagnostic reset function only once every 24 hours. For the controller to increment the 24 hour timer, you must maintain power to the controller. Cycling power resets all timers and counters.

After the controller detects the first special diagnostic, the unit waits 30 minutes before invoking the automatic diagnostic reset function. The automatic diagnostic reset function clears the special diagnostic and attempts to restore the controller to normal operation. The controller resumes normal operation until another diagnostic occurs.

Note: The automatic diagnostic reset function does not operate during the manual output test sequence.

If a special diagnostic occurs within 24 hours after an automatic diagnostic reset, the controller must be manually reset. Other pos- sible methods of resetting diagnostics are described in the sections that follow.

Use the controller’s Test button during installation or for troubleshoot- ing to verify proper end device operation. Press the Test button to exercise all outputs in a predefined sequence, the first of which will attempt to reset the controller diagnostics if any are present. See Table 13 on page 49 for more information about the manual output test.

Cycling Power to the Controller

After removing and reapplying the 24 VAC power from the board, the unit cycles through a power-up sequence. By default, the controller attempts to reset all diagnostics at power-up. Diagnostics present at power-up and those that occur after power-up are handled according to Table 14 on page 50.
