Bought this today, brought I home and spent two hours installing it. Not a drop of water, hot or cold would come out of the faucet. Of course I assumed that it was a water issue, and after checking my water supply, it had to be a problem with that sensor. I reset the sensor exactly as explained on the paperwork by disconnecting the cable from the power supply for 10 seconds and then 
reconnected. I could hear the sensor resetting but still no water, hot or cold. I also checked the wire coming down from the sensor and the water quick disconnect. Both were secure. Additionally the manual said to refer to the quick start guide and there wasn’t one. After another hour of frustration, I took the entire thing out and will be returning it tomorrow. I knew better than to buy a faucet that requires batteries and a sensor. Really aggravating and costly.
