@BJ 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, if you can include the full text of the error or warning message from the simulation tool, that would be helpful.

@BJ just FYI comments are limited to ~500 characters. You can update your post to add more information like error or warning messages.

The Setpoint manager error makes it sound like you haven't connected a thermal zone to the demand side of a central air loop in the HVAC Systems tab.

Thanks Aaron for the feedback. I think I did connect the thermal zone. Is there away I can upload the OSM file here?

@BJ if you have trouble attaching files to posts, you can save files on Dropbox, Google Drive, etc. and then share a link here on Unmet Hours.

The SetpointManager:SingleZone:Reheat needs to know what zone inlet node is used to determine the air mass flow rate for calculation of the set point temperature. That field is a required field. For SPM = Setpoint Manager Single Zone Reheat 1, check that the field 1) is not blank, and 2) has the correct name of the zone inlet node you want to use.

SetpointManager:SingleZone:Reheat,
  A5 , \field Zone Inlet Node Name
       \required-field
       \type node

Thanks for your reply. Really appreciated. I have figured that out yesterday, it seems one of the space that the SPM connected to was blanked, however the heating and cooling schedule was assigned to that space but the SPM was not able to read that till I changed the space/ zone.
