HCPFC protection

Name in the manufacturer's documentation (service manual): PFC protection[1]

In plain words (editorial)

PFC protection. The service manual names poor power grid quality (sharply fluctuating AC input voltage), an unreliable connection of the power plug, wiring board or reactor, very dirty heat exchangers or blocked air inlet/outlet, or a damaged outdoor main board.

When to call a service technician: Make sure the air inlets/outlets are not blocked and the unit is clean; if the code returns, call a service technician.
