Sometimes you need to add new temperature in your project for at least 3 reasons :
- When you use SI units Revit default fluids are bugged. I have seen them bugged for more than 5 years… Templates were made in Fahrenheit and some temperatures just don’t work when converted into °C or K.
- Revit default fluids don’t have enough temperatures. About 5K between each and they usually just don’t fit the temperature you need in your project.
- Water, ethylene and propylene glycol are the only default fluid available.
