Condenser assembly temperature not reached
After the compressor has been on for 15 minutes, if the heat exchanger
temperature (Tbe for cooling and dehumidification, Tbi for heating) falls
below T_cfrl, the unit will trigger a CF/RL alarm (all outlets are
deactivated, the air outlet
louver
performs a self-calibration), commands
are no longer accepted (either from the remote controller or from the
display unit) and the corresponding alarm code (see table above) is
shown on the display.
This alarm may be deactivated in heating mode during defrosting.
The board may be reset only by disconnecting the power supply or by
sending a reset command over the serial port.
