Operation
Setting the Time
To set the current time, gently pull the dial outwards and rotate it until the current time aligns with the 'TIME SET' arrow. Ensure the dial is pushed back in after setting.
Setting On/Off Trippers
The time switch comes with one 'On' tripper and one 'Off' tripper. These trippers are small pins that are inserted into slots around the perimeter of the dial. Position the 'On' tripper at the desired time for the load to turn on, and the 'Off' tripper at the desired time for the load to turn off. Additional trippers can be purchased separately to allow for up to 12 'On/Off' operations per day.
Manual Override
The time switch features a manual override lever located below the dial. This lever allows you to manually switch the load 'On' or 'Off' without affecting the programmed schedule. Simply move the lever to the 'On' or 'Off' position as needed. The timer will resume its programmed schedule at the next scheduled 'On' or 'Off' event.
