If you pull the handle off all the way back to the valve body there is a little black stopper around the cartridge body that you can adjust by pulling it out and sliding around the cartridge body this enables people to just turn the handle to one setting and jumpping in to their favorite temperature. in your case it doesn't allow you to have any cold water. so turn it one way see if you get what you want or try the other or some of them you can even just take the darn thing out and not even have to worry about it

If you have single handle facute one bad cartridge in the system may be acting like a mixing valve and allowing cold water to mix with hot not allowing water to get hot enough .

If you aren't getting any error codes, then the heater is probably doing its job. Your problem is probably somewhere in your plumbing system. The most common reason you get this sort of problem is due to cold water mixing in the hot water system. There are a number of causes for a "cross connection" :

-Faulty check valve
-Missing check valve on reciculation return line
-Faulty shower cartridge
-Thermostatic mixing valve set too low
-Faulty thermostatic mixing valve
-Faulty anti-scald valve

The easiest way to confirm a cross connection is to: 1) shutoff the cold water entering the tankless heater 2) open hot water valves around the house. If you still have water flowing at your hot water fixtures, then you have a cross connection.

well you can do a 3 way shower valve , or a mixing valve with 2 control valves. or you can do just to regular shower valves one for each of the heads you want one for the rain and one for the shower head. this way is cheeper and you can have one on hot water and the other cold water or the other way around or both the same temp.
