(※1) ON Delay Time: Although it is ON condition, it is turned on after ON Delay Time.
(※2) Minimum ON Time: Once the output is on, it is not turned off during the minimum ON time even if it is under the OFF condition.
(※3) Minimum OFF Time: Once the output is off, it is not turned on during the minimum OFF time even if it is under the ON condition.
(※4) Delay Time between Steps: Under the condition that multiple steps are turned on simultaneously, the lead step is turned on first and then the next step is on after Delay Time between Steps.
(※5) Rotation: It controls all the units evenly according to the predetermined ON/OFF and step parameters.
※ ON Rotation: ON - It turns on from the step which is being off the longest. OFF - The step which was on by step ON pressure turns off if it reaches its step OFF pressure.
※ ON/ OFF Rotation: ON - It turns on from the step which was off the longest. OFF - It turns off from the step which is being ON the longest.
(※6) Refrigerant selection: Display saturation temperature in accordance with selected refrigerant.
(※7) Offset: Offset the differential for pressure sensor.
e.g) If displayed pressure value: 0.20MPa and actual pressure value: 0.22MPa. It is offset by inputting +0.02MPa.
