(Note1) Refer to the section "1. Checking the error history" for further information. (Page 111)
(Note2) Codes c01 through c11,c14,c37 and c38 indicate temperature sensors.
(Note3) Codes c12 and c13 indicate pressure sensors.
(Note4) Codes c15 through c18 indicate current sensors.
(Note5) Codes c19 indicate voltage sensor.
(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) Codes c29 and c30 indicate the degree of LEV opening.
(Note11) Code c32 indicates superheat that was calculated based on high pressure and discharge refrigerant temperature.
(Note12) When the input type is selected. When the input type is not selected = 0.
(Note13) c34,c35 and c36 show the external analog input values (water temperature settings)
(Note14) Effective when the value for item code 1080 is a value other than 0
