Error Code And Led Display; Error Code Displayed On Dx-Coil Unit Remote Controller - Mitsubishi Electric GUG-01SL-E Handbook

7-3 Error code and LED display

An error code displayed on the remote controller (PZ-01RC or PZ-61DR-E) or the M-NET system controllers,
and blinking or illumination of LED11 (green) on PCB B of the Dx-coil unit show the type of an error.
This system is comprised of each control circuit of the Dx-coil unit (PCB A and PCB B), Lossnay unit, and
outdoor unit. If an error occurs, an error code is displayed on the connected remote controller. However, error
codes to be displayed differ depending on error locations and the connected remote controllers.
• Dx-coil unit remote controller (PZ-01RC) uses two-digit codes to indicate errors detected on PCB A of the Dx-
coil unit or in the outdoor unit. Whatever error detected on PCB B of the Dx-coil unit or in the Lossnay unit is
displayed by the error code "P1."
• Lossnay remote controller (PZ-61DR-E) or M-NET system controllers use four-digit codes to indicate errors
detected on PCB B of the Dx-coil unit or in the Lossnay unit. Whatever error detected on PCB A of the Dx-
coil unit or in the outdoor unit is displayed by the error code "0206."
When Lossnay remote controller (PZ-61DR-E) or M-NET system controllers are not connected, error details
can be checked by LED11 (green) on PCB B of the Dx-coil unit.

Cause
See (1).
When Lossnay remote controller (PZ-61DR-E)
or M-NET system controllers are used, check
an error code displayed on them. → See (3).
If none of them are used, check LED11 on
PCB B of the Dx-coil unit. → See (2).
Check an error code displayed on Dx-coil unit
remote controller (PZ-01RC).
If the error code "P1" is displayed, check cable
connection or power supply referring to the er-
ror code "0206" troubleshooting. → See (3).
