@ecem what simulation tool are you using? Please mention it in the title or body of your post, as well as add a tag so that others can provide better help.

Also, any images to explain the behavior you're seeing would be helpful.

Finally, can you upload your model to Google Drive, Dropbox, etc. and then share a URL for others to download? That would help others provide better solutions.

I believe this is the case for any schedule. A step-by-step:

  • STEP 1 : Click on the bottom-pointing arrow of the Lower Limit field, as desired (e.g. -10°C)
  • STEP 2 : Drag a selected horizontal band down to the desired low temperature
  • STEP 3 : IMMEDIATELY save the model (e.g. CTRL-S) ...this is key!

You should be able to navigate elsewhere (e.g. to another tab), then return back to the modified schedule.


EDIT : Thanks for sharing the .osm file. I had no difficulty adjusting the scheduled setpoint temperatures below 0°C.

Using OpenStudio Application 1.9.0-rc1 on MacOS 15.5 (latest).

just upper limit change this way. I m using, schedule type:temperature, numeric type: continuous, lower limit: none, upper limit: none. then I try to assign values for dual setpoint. but just upper limit works. lower lmiti does not stick, even though I saved multiple times.

I use horizontal band but, the value goes to upper limit, always. I want to create an interval between 15 and 18. but did not work.

Hmmm. OpenStudio version? Consider sharing a (public) link to your .osm file, as suggested by @Aaron Boranian.

Sorry @ecem, can't reproduce your issue with the linked .osm file (see above EDIT).
