操作手順
The T174 uses a mechanical dial and trippers to set the ON/OFF schedule.
現在時刻の設定
- Rotate the timer dial clockwise until the current time aligns with the "TIME SET" arrow or indicator on the timer mechanism.
- Ensure AM/PM is correctly observed if the dial has such markings.
オン/オフ時間の設定
The timer comes with two trippers: one "ON" tripper and one "OFF" tripper. Additional trippers can be purchased separately (Extra Trippers 11Z965).
- Locate the "ON" tripper (typically silver or light-colored) and the "OFF" tripper (typically black or dark-colored).
- Snap the "ON" tripper onto the dial at the desired time you want the connected device to turn ON.
- Snap the "OFF" tripper onto the dial at the desired time you want the connected device to turn OFF.
- You can set up to 12 ON/OFF cycles per 24-hour period using additional trippers. The minimum time setting is 1 hour.
