Re: [TRNSYS-users] Problems with type 33

[knut.erik.enerstvedt@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
