A touch panel equipment for air conditioning has a plurality of electrodes arranged in two-dimensional matrix, a touch sensing IC for scanning capacitance of the electrodes, and a touch panel controller for deciding a touch position from the capacitance sensed by said touch sensing IC. The touch panel controller resets the touch sensing IC when the capacitance of the electrodes located in a check area is not changed during predetermined threshold timings, and does not reset the touch sensing IC when the capacitance of the electrodes located in the check area is changed within the threshold timings. As the touch panel controller resets the touch sensing IC due to the change of the capacitance value of the electrodes located in the check area, the resetting operation is operated automatically so that the touch panel equipment could avoid the user's external work.
