Parameter Point Check Table
Press “Check” button to see system available parameters. When pressing for the first time, the display
will show you a sequence and at the end of 1 minute, the parameter value will appear. When pressing
a second time, the following sequence appears.
For normal status display, the last 2 digits appear under the following conditions:
i. Unit is not in operation (delay mode); “outdoor ambient temperature”.
ii. Unit is in operation; “compressor frequency of operation” will be displayed.
After a 20 second delay under the same parameter, the display returns to its normal state.
If a system protection is active, the first digit indicates “status code”.
