15.9 Parameter Point Check Table

To display system parameters, press the "Check" button to index through

the series of parameters available. The first 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. Refer to Figure 44 and 45 for check button location on
the control board.
Normal Status, last two digits will display under the following conditions

i. Unit not operating (Standby Mode); "outdoor ambient temperature".
ii. Unit operating; displays "compressor operating frequency".
 After 20 seconds on same parameter, the display will revert back to
normal status.
If a system protection is active, first digit will display "status code".
