風機盤管電動二通閥（三線兩控）不工作時處於常閉狀態，當需要工作時，由房間溫控器提供乙個開啟訊號，使電動閥接通電源而動作，開啟閥門，冷凍水或熱水進入風機盤管，為房間提供冷量或熱量；當室溫達到房間溫控器設定值時，房間溫控器令電動閥斷電，復位彈簧動作使閥門關閉，從而截斷進入風機盤管的水流。通過閥門關閉和開啟，使室溫始終保持在房間溫控器設定的溫度範圍內 retz electric two-way valve (three-wire two-way control) of fan coil is normally closed when it is not working. when it needs to work, the room temperature controller provides an opening signal to make the electric valve act by connecting the power supply, and open the valve. chilled water or hot water enters the fan coil to provide cooling or heat for the room; when the room temperature reaches the set value of the room temperature controller, the room temperature controller will cut off the electric valve, and the return spring will act to close the valve, thus cutting off the water flow into the fan coil. by closing and opening the valve, the room temperature is always kept within the temperature range set by the room temperature contro
