(Note1) Refer to the section "1. Checking the error history" for further information. (Page 105)
(Note2) Codes c01 through C11 and c14 indicate temperature sensors.
(Note3) Codes c12 and c13 indicate pressure sensors.
(Note4) Codes c15 through c18 and c20 through 22 indicate current sensors.
(Note5) Codes c19 and c23 indicate voltage sensors.
(Note6) Codes c24, c31, and c33 indicate target values.
(Note7) Code c25 indicates compressor's operating frequency.
(Note8) Code c26 indicates superheat that was calculated based on the low pressure and suction refrigerant temperature.
(Note9) Code c27 indicates superheat that was calculated based on the low pressure and shell temperature.
(Note10) Code c28 indicates the operating frequency of the fan.
(Note11) Codes c29 and c30 indicate the degree of LEV opening.
(Note12) Code c32 indicates superheat that was calculated based on high pressure and discharge refrigerant temperature.
