Management device and heat source system

A management device and a heat source system are provided. Provided is a device management system that reduces useless change operations relating to the capability of a specific device without complicating a heat source system. A facility management device (50) manages a heat source facility (10), which is a specific facility that changes the state of a heat medium circulating in a heat source system (1). The state value of the heat medium measured by an outlet temperature sensor (63) of the heat source system (1) is received, and the capability change operation of the heat source equipment (10) is prohibited according to a parameter related to the change of the state value. 提供管理装置和热源系统。提供不使热源系统复杂化而减少与特定设备的能力有关的无用的变更操作的设备管理系统。设备管理装置(50)对使在热源系统(1)中循环的热介质的状态变化的特定设备即热源设备(10)进行管理。接收热源系统(1)具有的出口温度传感器(63)计测出的热介质的状态值，根据与状态值的变化有关的参数，禁止热源设备(10)的能力的变更操作。
