During commissioning, a timing program can be created within the block to manage all air conditioner controls at specific times or dates. When the VRF system is set to a particular value or control at these scheduled intervals, it effectively locks those settings. The outputs of these locked controls can be displayed on the UI as status information.</p><p>The lock states are only visible within the <strong>VRF Basic</strong> interface, which can be accessed by enabling the “Show VRF Page” option from the <strong>Settings / System</strong> menu.</p></td></tr><tr><td><img src="https://2866306475-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FsOJKIPVBwStiyHDRNL5F%2Fuploads%2FShJIrEjJo8wVFpFunEop%2FSchedule.png?alt=media&#x26;token=e67bb65e-260c-445b-8524-b538528c008d" alt="" data-size="original"></td><td><strong>Schedule</strong></td><td><strong>The schedule</strong> activates according to the time and frequency defined within the block.
