Re: Sanyo VRF Error L18
During heating operation (Comp. ON), the highest detected temperature at an outdoor unit
heat exchanger (EXG 1, EXG 2, EXL 1, or EXL 2) was 20°C or more above the outdoor air
temperature (Air Temp.) continuously for 5 minutes or longer, or the detected suction
temperature (SCT) was 20°C or more above the outdoor air temperature continuously for
5 minutes or longer.
Check sensors.

4-way valve operation failure
During heating operation (Comp. ON), the highest detected temperature at an outdoor unit
heat exchanger (EXG 1, EXG 2, EXL 1, or EXL 2) was 20°C or more above the outdoor air
temperature (Air Temp.) continuously for 5 minutes or longer, or the detected suction
temperature (SCT) was 20°C or more above the outdoor air temperature continuously for
5 minutes or longer.
(1) The 4-way valve connector (20S CN022) has become disconnected from the control PCB.
(1) Check the 4-way valve connector (20S CN022).
If the connector is normal, correct or replace the problem locations
summary is a bit vague

Without checker for ECO hard to find that error, but you can see all parametrs from wired controller.
