Issa, I am not sure that I follow what you are trying to do but you can set the radiative power of a heating type in TRNBuild as an input to Type56 and you can define the zone's operative temperature as an output. You can then use whatever controller component you want to adjust the radiative power so that the zone operative temperature stays near a set point. Kind regards, David
