Hello There,
Thank you for the help in advance.
I'm trying to apply Window type AC unit in my energy model. The model works, but the issue is with my heating setpoint. Even-though I'm using dual set points the model, cooling 20C and heating 15C. The system does not work in January where the temperature is less than 15C. In other words, the model does not consider my heating setpoint and does not preform heating. The indoor air temperature (IAT) is fluctuating in the beginning of the year (Cold weather) and no heat setpoint seems to be working, until IAT reaches the cooling set point, then it goes in a straight line. When the IAT is less than the cooling setpoint and less than the heating setpoint, the heating system does not work.
