n.水温自动调节器
Aquastat must be used to maintain water to fixtures at a desired temperature and to eliminate temperature override during no draw periods. 必须采用水温自动调节器来维持用水设备所需的水温，消除没有流动时期的过高温度。
AQUASTAT Country Profiles describe the state of water resources and agricultural water use with special attention to the water resource, irrigation, and drainage sub-sectors. AQUASTAT国家概况描述水资源和农业用水状况,特别注意水资源和排灌分部门。
NOTE: Recirculating control aquastat must be set at least 5oF to 10oF lower than the temperature setting of the Series N170-M2 valve, otherwise the recirculator will run continually. 注：再循环控制水温自动调节器的温度设置必须比系列N170-M2阀门的设置温度低5至10华氏度，否则，再循环器将会不断运行。
