Restricts the water flow
I purchased two of this US9 Busch 3000 series for two showers. I used a 8/3 gauge wire with a 40 Amp breaker. When I was flushing to get all the water bubbles, I noticed that the water coming in had a lot of pressure but in the way out the water flow was to restricted, I let it run for about 10 minutes and never changed. I tried the sink faucet and ir responded right of way, but the water flow was to low. Every time I shower, I have tried starting on cold and reach the desired temperature and it starts to get hotter and hotter that I have lower it until the flow stops and get ready for cold water. I have tried to open it full blast hot and the move it to the middle to even up the flow, and it works for few seconds, then you can feel the heat rises without moving the knob at all, the water heat gets so uncomfortable that I have to set it at 2 o´clock and it works for a few seconds, almost a minute, then it gets hot again. I lower it almost at a full could and it shuts down the hot water all of the sudden. Be ready for cold water. How can I solve this problem? Why my shower can´t sostain the same temperature throughout the shower time?

    Flow rate of water was restricted because of the aerator screen in the new American Standard faucet. This caused the flow rate sensor not to activate and therefore no hot water. After talking with the tech support rep Brian from Bosch and helping me troubleshoot the problem, we figured out it was the aerator screen in the faucet. Now it works great! I also like the thermostat on this US12 unit. This took me some time to install because working with 6 guage wire is not easy. I used 6/2 wire with ground. Don't use 6/3. The ground with the 6/2 is what you need. The hot water comes out scalding hot for the first 3 seconds then it starts to settle down to the right temp. I'm ok with this because before we didn't have hot water for 3 minutes. My water heater is on the opposite end of the house which is why I installed the tankless. I just installed this unite 1 hour ago. My experience with customer service and tech support was excellent. Delivery was great. I was able to track the package on the Home Depot website. I included some pictures.

      Provides warm water with the provided low flow faucet restrictor. Don't expect hot water…! I would buy again for use as a hand washing station.
