Need to review some of your inputs. The HW loop is set to STANDBY which means the pump will run whenever a system fan is scheduled on and the system's heating is available. Looking at your input, the HW loop is always on as system fans are on 24/7 and heating is always available. The PMZS units have gas furnaces with the cold deck control = RESET. The default hot deck control is CONSTANT at 120F as input. PMZS has a default minimum hot deck airflow of 1%. Each of these units is 100% outside air 24/7.<br>

I have an issue for my proposed design for my LEED model. It ends up using a significant amount of gas for heating during the summer. However, the baseline model is not using gas for heat during the summer. Does anyone have an idea for why this might be?</p>
