Thanks for your reply. I am not sure where this setting may be. I should explain that I am entering batch schedule of field temperatures for a few months of the year, a csv files. Lately I am trying to run it as ideal to verify unmet setpoint issues. All the hours of the year that are not accounted for in the 3 month field data has zeros. Also I had cooling not active on the compact schedules with those months having a zero instead of 1. The opposite for winter. I can change the zeros in the setpoint csv file to another value, but it sounds like you are pointing me to another place, I hope. Please let me know.
Thanks for the graphs.

Change your cooling setpoint from 0 to say 25 degrees, or at a minimum 3 degrees.
The concept is that a deadband of a minimum 3 degrees Celsius so that the heating and cooling do not "battle"...Your current cooling setpoint will try to keep the zone at 0 degrees Celsius, so would run all the time and the heat would run to keep the zone at 19.14 Celsius.If you are wanting to have no cooling than set your cooling to 100 rather then 0. With your cooling setpoint at either 100, 25 or 23 degrees your file will run.I have attached are some charts I made to show this for another project that you might find useful.. attachedBest-
