PURPOSE:To attain the titled remote display method with low cost by transferring the operation/drying state of a grain drying device to a TV controller and then transmitting and displaying said state to a home TV set from the TV controller via a switch connected to a broadcast reception antenna. CONSTITUTION:A grain drying device 1 consists of a motor group 1a which drives a conveyor, a fan, etc. and a sensor group 1b which detects the water content of grains, the hot air temperature, etc. The actuation of these groups 1a and 1b are controlled by a CPU2c via an I/O unit 2a and an A/D unit incorporated to an operation board 2. The data of the CPU2c are transferred to a TV controller 3 consisting of a TV CPU3a, a video signal generator 3b and an R/F conversion module 3c. The output of the controller 3 is connected properly to a home TV set 6 via a switch 4. Thus the data of the device 1 are displayed to the TV set 6.
