11.4 Check Point Values
To display system parameters, press the “check” button on the outdoor board
to index through the series of parameters available. The fi rst time you press the
“check” button, it will display the sequence, and after 1 second it will display the
value of the parameter. If you press the “check” button again, it will display the next
sequence.
After 20 seconds on the same parameter, display will revert back to normal status.

Table 26 Check Point Values
It is recommended to use the "check" button to verify outdoor unit
capacity (No. 0), operation mode (No. 1), and subcooling (No. 7 minus
No. 3 (will be within 2 degrees of measured gauge values)) prior to
leaving the installation site. See IOM for required subcool values.
