4、開關,控制箱處于制冷狀態(tài)時開啟水泵、制冷機、空調機組;當處于制熱狀態(tài)時開啟電加熱、空調機組;當處于通風狀態(tài)時開啟空調機組。面板上設自動啟動、停止按鈕,在制冷、制熱、通風任一狀態(tài)下自動啟動、停止按鈕有效,空調機組處于手動狀態(tài)時,自動按鈕無效;3、消防信號、防火閥信號關閉機組。4、1#2#空調機組只要有一臺處于自動狀態(tài)時,制冷、制熱、通風轉換開關有效,1#2#空調機組都處于手動時制冷、制熱、通風轉換開關無效。5、制熱狀態(tài)時根據(jù)回風溫度控制電

5、加熱啟停,電加熱與風機連鎖,風機不啟動,電加熱不啟動;風機電加熱段設高溫報警傳感器,當電加熱段內溫度超過75(參數(shù)可調)時,自動切斷電加熱。6、制冷狀態(tài)時,先啟動空調機組,再啟動水泵,最后啟動制冷機組;本控制只提供制冷機啟停干接點信號。制冷狀態(tài)因空調機組無電動水閥,故無法實現(xiàn)溫度制動控制;7、通風狀態(tài)啟動風機。Functionsoftheunit:1.Theairconditioningunitisequippedwiththemanu
