Input:
Question: Can the run time be adjusted after activation?  I saw two different answers for how long it runs? Does that mean it can be adjusted?
Document: I would rather install an undersink heater to do this job or get the hot water circulation pump to effectively use this.
don't know if it saves water yet but I do know that the sensors work. I received it fast. Another item needs to be bought so that it can have warm water or else it will only be cold or hot. the item that needs to be bought will be suggested. I bought it. the company was good- the item didn't work and they send me one lightning fast.
Installed with batteries, Used the Lithium Camera batteries so I don't have to change them. I noticed to hard wire it was setup for 220V and had some sort of European plug on it. Not an electrician, but I didn't feel like tackling it. In the manual it said that at 30 uses per day the batteries would last 2 years.....we'll see. Like it so far.
