[TRNSYS-users] Problems with type 33

[knut.erik.enerstvedt at niva.no]

Dear Ivan,

It is likely that this error is caused by some of the inputs to Type 33. I 
suggest you check the data in your weather file for unrealistic values. 
The source of the error can also be some other component which calls the 
PSYCHROMETRICS routine, for example Type 56 and various HCAC components. 
In the List-file, where the error is mentioned, there should also be Type 
and/or unit number for the component(s) caussing the error. If you find 
any other components listed here, I suggest you check their inputs with an 
online plotter. Try to notice the time when the error occurs, if this 
coincides with turning on heating/cooling, for example.

Hope that some of this turns out helpful.

Best regards,
Knut Erik Enerstvedt
