Cogeneration system, display device for cogeneration system, and control method of cogeneration system

摘要

PROBLEM TO BE SOLVED: To provide a remote control device for simply displaying the process of hot water to be stored in a cogeneration system for making hot water with high energy saving performance using the exhaust heat during power generation, and storing the hot water in a hot water storage tank.SOLUTION: In a fuel cell system 11 including a fuel cell unit 12 for generating power using fuel gas and oxidant gas, a controller displays a first sign having a different shape from a first scale in a part where the first scale is displayed on a display part of a remote control device 20 when a first temperature detector 17 detects a display of less than a first temperature when the fuel cell unit 12 generates power.
