After completing the setting, the value is automatically saved within 5 seconds and starts running. Time Range: The time range switches automatically. Default unit is seconds. When decreasing from 0, it changes to 99.9s; when increasing beyond 999, it changes to 0.0.0. Number Format: X.X X — Time range 0.01s X X.X — Time range 0.1s X X X — Time range 1s X.X.X — Time range 1min Example: Setting T1=8.88 means countdown in 0.01s increments; T2=8.8.8 means countdown in 1-minute increments. Working Mode Settings: 6 working modes available: Long press the Set button to enter P-0 parameter, then use Plus or Minus buttons to select the desired mode. P-0: Relay turns off after delay T1, then stops. P-1: Relay turns on after delay T1, then stops. P-2: Relay turns on after delay T1, turns off after delay T2, then stops. P-3: Relay turns off after delay T1, turns on after delay T2, then stops. P-4: Relay turns on after delay T1, turns off after delay T2, loops continuously. P-5: Relay turns off after delay T1, turns on after delay T2, loops continuously. Typical Application: To set a delay of 4.05 seconds followed by a 10-minute delay before stopping: Set T1 = 4.05, T2 = 0.1.0 Set working mode to P-3 Settings are automatically saved within 5 seconds and begin running.
