This research concerns a room temperature control experiment using a PTC floor heating system. It aims at development of control techniques for the PTC heater in the room, which is assumed to be part of a house. In this report, a control technique taking into account the heating load was developed based on the PI control technique in order to remove the room temperature offset. As a result, the offset was removed and it was shown clearly that PI control is effective as a control technique for a PTC floor heating system.
