13.8 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 30 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”.
No.
