An apparatus control system is provided with a skin-temperature measurement device for measuring skin temperature, and an apparatus control device for controlling an air conditioning apparatus. The apparatus control device includes a storage unit for storing an association table (association relationships) of skin temperature and control content for the air conditioning apparatus. The apparatus control unit controls the air conditioning apparatus in accordance with the control content that is associated with a first skin temperature inputted into the input unit and is stored in the storage unit. Thereafter, when a second skin temperature newly inputted into the input unit does not fall into a comfortable temperature range, an update unit updates the association table stored in the storage unit. When doing so, the update unit adjusts the control content in the association table in the direction which reduces an excess/deficiency in the control based on the control content.
