recirculator

基本解釋

Because very little hot water is required to maintain the low temperature in the mains (usually 140oF), a relatively small capacity recirculator can generally be specified.
由於衹需要很少的熱水來維持主琯道的低溫度（通常爲(wèi)60oC），通?？赡苄枰付ㄒ粋€相對較小功率的循環(huán)器。
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：再循環(huán)控制水溫自動調(diào)節(jié)器的溫度設(shè)置必須比系列N170-M2閥門的設(shè)置溫度低5至10華氏度，否則，再循環(huán)器將會不斷運行。
