Troubleshooting

Diagnostics

The controller is equipped to display a diagnostic code through the interface module; if the display is not present (Class 2 control), there is no method to retrieve the diagnostic codes from the unit.

If there is no interface module to indicate the presence of a diagnostic, service will only be triggered by a comfort or operational complaint.

The controller will only display the most severe diagnostic present.

Translating Multiple

Diagnostics

The controller senses and records each diagnostic independently of other diagnostics. It is possible to have multiple diagnostics affect the operation of the unit, but only the most severe diagnostic will be displayed.

Resetting Diagnostics

A reset clears any latching diagnostics and allows the control to try to run the PTAC normally. If the latching condition is still present after the reset, the control will shut down the PTAC. A reset will reset a unit that is running normally. A reset is just like cycling power to the unit.

There are two ways to reset diagnostics:

1.Manual output test at the controller

2.Cycling power to the controller

Manual Output Test

When manual test has been initiated, the controller exercises all outputs in a predefined sequence. The last step of the sequence resets the controller. See the Manual output test section on page 22 for more information about the manual output test.

Cycling Power

When someone turns off the controller’s power, then re-applies power, the unit cycles through a power up sequence. By default, the controller will attempt to reset all diagnostics at power up. Diagnostics present at power up and those that occur after power up will be handled according to the defined unit diagnostics sequences (see Diagnostics table below)
