I am trying to model a residential building which is designed with a boiler and radiator. However I have created hot water loop including boiler and two individual radiators for seperate rooms. But I have problem when simulating model as' mismatch variable (temp )'. Also program forced me to put sensors then I have placed sensors to room input and output line. But still same problem exists.
Do you have any idea about this?
