Error codes

The error codes shown in the table below will be visible in the INDOOR UNIT display whenever an error is detected from the OUTDOOR

UNIT. ALL errors will stop the compressor from running until the error is solved. Some errors are automatically cleared, some needs man-

ual action and some severe errors might even need hardware to be replaced or serviced. Follow the superscript to below the table for

further information.

It takes a minimum of 3 minutes for the compressor to start from a

standstill.
