Quick Setup Guide
- *Connect Power* Wire AC 110220V to power input terminals
- *Connect Load* - Connect device to relay output (NO/NC/COM)
- *Power On* - Unit initializes with LCD display active
- *Set Time Unit* Long press SET, select P00/1/2 for seconds/minutes/hours
- *Set Operating Mode* Navigate to P1 and select 05 mode
- *Set T1 Value* Press SET to enter T1, adjust with +/ buttons
- *Set T2 Value* Press SET again to enter T2, adjust with +/ buttons
- *Save Settings* Wait 6 seconds for autosave[citation:1][citation:6]
All settings auto-save after 6 seconds of inactivity[citation:1][citation:6]
Use T1 for first timing period, T2 for second timing period[citation:6]
Verify correct wiring before applying power
