Frequently Asked Questions
1. Does the UNS Micro Solenoid get hot while running?
No. Thanks to its 12V DC low-voltage transformer, this solenoid consumes minimal power and stays cool to the touch even after running continuously for 8+ hours.
2. Can I connect this solenoid to a smart home plug?
Yes. The power adapter plugs into any standard 110V–220V AC outlet, making it fully compatible with traditional mechanical timers, digital outlet timers, and Wi-Fi smart plugs.
3. When should my solenoid turn CO2 on and off?
We recommend programming your timer to turn the solenoid ON roughly 1 hour before your aquarium lights turn on, and OFF 1 hour before the lights turn off so plants have saturated carbon ready at photoperiod start.
