Sequential AC Cyclic Timer Switch
This Digital Air Conditioner Cyclic timer is a very flexible timer allowing you to digitally set the desired On and Off periods independently. The timer stores the current settings in non-volatile EEPROM memory, so no need to program again. Also stores the running time in EEPROM to continue the remaining time once power resume. Time ranges from 1-999 seconds, 1-999minutes & 1-999 hours.
Once the timer has been configured with the required time periods, the timer will start counting down displaying the remaining time of the current period. An LED will indicate whether the timer is in the On period or the Off period.
The timer stores the preset time periods and current settings in non‐volatile EEPROM memory, so the last preset time periods are easily recalled even if power is disconnected from the unit. The bright LED display as well as three push buttons are incorporated right on the board allowing it to be panel‐mounted easily.
It has the following modes of operation:
1. ON mode: The device connected will be ON for the programmed Time period and then gets switched OFF.
2. OFF mode:The device connected will be OFF for the programmed Time period and then gets switched ON.
3. ON-OFF CYCLIC: The device connected will be ON for the programmed-on period and then gets switched OFF for the programmed off period. This sequence will repeat in a cyclic pattern.
4. OFF-ON CYCLIC: The device connected will be OFF for the programmed off period and then gets switched ON for the programmed-on period. This sequence will repeat in a cyclic pattern.
