PROBLEM TO BE SOLVED: To provide a controller for a greenhouse, having a shortened wired length to reduce a wiring material and a construction cost, and standardized functions by assembling the functions at each terminal to facilitate the addition and change of the functions. SOLUTION: CPU (central processing unit) terminals S are arranged at the vicinities of each sensor such as a temperature sensor 5, a humidity sensor 6, and each limit switch 10, 12, 14, or the like, for detecting a target position, and input and output wires of the sensors are connected to the CPU terminals S. The CPU terminals S are arranged at the vicinities of each actuator such as a motor 7 for side windows 2 for controlling the opening and closing of the side windows 2, a motor 13 for curtains 5 for controlling the opening and closing of the curtains 5, and a motor 11 for ceiling windows 3 for controlling the opening and closing of the ceiling windows 3, and the actuators are connected to input and output wires. One controller 9 for watching/controlling the many CPU terminals S is arranged, and the controller 9 and the CPU terminals S are wired by crossover-wiring by using communication wires 63.
