I have a question about this field.

  1. Can someone use a example to explain what happens to the multistage coil and multispeed fan when this field is set to "Yes" or "No"?

For example. when this field is set to "Yes", and the system load falls between stage 1 coil capacity and stage 2 coil capacity, what happens to the coil in a HVAC time step? what happens to the multispeed fan in a HVAC time step?

What happens to coil and fan when this field is set to "No"?

2 . For the coil type restrictions, does it apply to "Yes" or "No"?

Following is the screenshot of the I/O document: Explaination of Single Mode Operation in I/O Document
