I am new in EnergyPlus and I wanted to set a temperature of a house model at specific heating and cooling setpoint. When I use single heating mode in the example file Packaged Heat Terminal Pump and use a weather file, the zone temperature goes beyond the heating setpoint temperature even if the heating coils are turned off. I even tried by turning off the fan, but the temp increases in the middle of the day beyond my heating setpoint. I also tried the EMS and tried to give a deadband in heating setpoint. I donot understand why my zone temperature is above heating setpoint when outdoor temperature is lower than the heating setpoint and my heating coils off.

I hope you could help me in this confusion.

Check internal loads for a misplaced decimal. Could try a copy of model with all internal loads removed to see if that is the cause.

Thanks David. When the internal loads are removed, EMS and heating setpoints works fine. So, What should I do to maintain a house in constant heating setpoint temperature with the load. I would like to use single heating mode, without turning the cooling on in winter period.

Sounds like either their is a mistake in an internal load that is excessively high, or you may need cooling if you want to maintain the temperature.

Make sure you did not set people activity schedule to the Number of People Schedule Name in class of People. I taught E+ and came across several these mistakes resulting a 0 heating design load .
