Brushed Nickel Dual Function Faucet FAQ
Power Management, Electronic Control & Solenoid Performance
Which electrical configuration supports uninterrupted operation during power interruptions?
An AC/DC power arrangement allows automatic changeover to battery operation when primary electrical power is unavailable.
What function does the electronic controller perform during each activation cycle?
It processes infrared sensor signals and coordinates both the soap pump and water solenoid for accurate dispensing.
Why should low-voltage wiring remain isolated from plumbing connections?
Proper cable routing helps protect electronic components from moisture exposure and simplifies future maintenance access.
Which diagnostic indicator often signals declining battery capacity?
Slower sensor response or inconsistent activation may indicate that backup batteries require inspection or replacement.
