Whenever this table is updated, the installation test procedure, and the alarm output function should
be updated.
Only one code is shown.
Order of priority is 1-32. Diagnostics is continuously ON as long as power is on.
Heat Sink Over Heating Protection, Compressor Over Heating Protection, and System Over Power
Protection are declared only whenever in 'Stop-Compressor' status.
All faults, except the thermistor faults, will remain at least 10 seconds. This rule comes to serve the
monitoring utilities, in a case the fault is released quickly it will be still shown under the monitoring
utilities.
Thermistor faults are reported only when they are enabled.
When the outdoor unit is in fault (not protection), an in-fault signal is sent to the indoor. When all the
outdoor unit faults are cleared, 'no-fault' signal is sent to the indoor.
