Welcome to the TRNSYS Users Forum.
The forum is a place where people can interact and have discussions about different topics involving the use of the TRNSYS software package. Here you can post topics for discussion or questions on using TRNSYS and get advice from other users or TRNSYS experts. This forum is not intended for detailed technical support. Users should contact their distributor’s hotline for such assistance.
Some tips for success on using the forum:
- Follow the Forum Rules posted in Forum Administration.
- There are categories for different types of topics and questions. Post your topic or question into the proper category.
- Before posting a topic or question search the existing topics (and the TRNSYS Users listserv archive or Post archive) to see if a similar topic or question has already been answered.
- Use a descriptive topic name. Don’t use attention getting subjects, they don’t get attention and only annoy people.
- State the version of TRNSYS and which add-ons your are using.
- Include enough specific details for your topic of question to be answered. Just posting “Why am I getting an error?” without describing the specific error and what you are trying to do when you get the error will not receive a response that fixes your issue.
- Remember when people help you, they are doing you a favor. Be patient, help people out by posting good descriptions of what you need help with, and be polite even if a response does not solve your issue.
- Moderators may edit your post for clarity or move your topic to a more appropriate category.

@jll there might be a couple changes that you need to make. One is that modifying the source code doesn't change the compiled version of the source. Y...
@jll I can think of a couple ways to interpret "previous week" and the answer to your question depends a little on the definition. If the "previous...
@tm-abir-ahsan Abir, I think you're correct that there is an error in the code. Those units should all be PR4 instead of PR2. The error doesn't impa...

@tonical I would recommend using Type25. That printer component allows you to set the time at which to begin printing (8760 in your case) the time at ...
@hyeontak-kim Hyeontak, that warning is not something about which to be concerned. Many TRNSYS components set three letter codes (for instance a ma...
@majadanovska Maja, it sounds like you are on the right track. I suspect that you might have used the quantity integrator (Type24) with a printer (T...
