＊1: When set to “1”, history is cleared. After clearing, the value is automatically reset to “0”.
＊2: Refer to the below table about the Capacity control pressure setting conditions.
Do not change the setting of F items that are not specified in the table above.
● Capacity control pressure setting conditions
Type Setting conditions (Example of Pressure setting 1)
Fixed-speed
① F023 shall be set F024 +3 psi (0.02 MPa) or higher, and F025+3 psi (0.02 MPa) or higher.
Variable-speed
① F023 shall be set F022+3 psi (0.02 MPa) or higher.
② F024 and F025 shall be set F022 or lower.
Note 1: The same setting condition is applied for Pressure Setting 2 (F031 to F034).
1. Pressure setting when minimum air receiver tank is installed ( 5.4.4)
Vtype : Pressure differential between cut-out and cut-in shall be 7 psi (0.05 MPa) or more, and pressure differential between
cut-out and target shall be 3 psi (0.02 MPa) or more.
Fixed speed type : Pressure differential between cut-out and cut-in shall be 15 psi (0.1 MPa) or more.
2. External selection of Cut-in/Cut-out pressure combination 1 or 2 is an option. (F018-2)
