[TRNSYS-users] Error with Psychrometric Routine?

[David Bradley]

Fred,
   perhaps I need to see the project. If you are passing 22.2 dry bulb 
and 14 wetbulb to Type33, it should just be spitting back the exact same 
thing with a calculation of RH. I just tried that and I'm getting an RH 
of 40% at 1atm pressure. When you say there is a 6.8C wetbulb, is that 
on the other side of the energy wheel?
