I have a Bosch tankless hot water heater: Confort S11 13 LP gas. I am supplying it from a cistern with a booster pump located 3 floors above. The water is too hot. If I mix enough cold at my single tap shower (with a 6-inch head) by the time I can tolerate the temp, it shuts off. Is their any way of regulating and lowering the max temperature. This is scaldingly dangerous.
Look for a water temp control on unit. Otherwise a lower temp can be attained by having a higher water flow to minimize temperature buildup in heating coil.

Tankless heaters do not like back pressure from anti scalding devices in shower controls. Every time they compensate and shove more coldwater to the hot side so you don't get burned when someon is using the cold water elsewhere in the home, it can reduce the heater below it's minimum flow rate and shut it down. Nothing wrong with the heater. Ask kohler if there is a wy to disable the device without buying a new unit entirely.
