Frequently Asked Questions

What is the input and output voltage for the CN101A timer?

The CN101A timer is designed exclusively for 12V DC systems. Both its power input and switched output terminals are rated for 12V DC. It is critical not to connect it to AC mains voltage or a different DC voltage, as this will damage the unit. The output can handle a maximum continuous current of 16A on a 12V DC circuit.

How do I program the weekly schedule on this timer?

Using the buttons below the LCD screen, you can set the current time and date. You then enter programming mode to define up to 16 separate ON and OFF events. Each event is assigned a start time and day(s) of the week. The timer offers 15 preset daily program combinations (like Weekdays Only or Weekend Only) to simplify setting complex weekly schedules for repetitive automation tasks.

What happens during a power cut? Does it keep my schedule?

Yes, the timer has an integrated 1.2V rechargeable lithium battery backup. When main 12V power is lost, this battery powers the internal real-time clock and memory, preserving all your programmed schedules and the correct time. The battery can maintain this memory for up to 180 days. It recharges automatically when main power is restored.
