Good morning, my model presents the following error, I have been investigating and I can't find any question in the forum in which it appears and I don't understand where it can come from (it could be from the hot water).

Could you tell me how to solve it?

** Warning ** "WATER FIXTURE" - Target water temperature should be less than or equal to the hot water temperature error continues...

As the error explains your temperature in your water fixture cannot be higher than the hot water that comes from your source which makes sense. So in terms of openstudio, the schedule that you use in loads tab-->Water Use Equipment Definitions-->Target Temperature Schedule cannot be greater than the setpoint manager in the plant loop that provides the hot water. As a visual example the setpoint manager here: Setopint manager of plant loop

should be greater or equal to the this schedule image description
