The utility model discloses an it realizes that self -checking function's air can central air conditioning machine to possess cybernetic loop pump, place the inside control circuit of above -mentioned device in and in including central air conditioning off -premises station, circulating pump, indoor wind dish, circulating line. Control circuit includes singlechip control circuit, temperature measurement circuit, circulating pump control circuit, central air conditioning off -premises station compressor control circuit and is the power supply circuit of above -mentioned circuit power supply. Single -chip control circuit controls the circulating pump control circuit and the central air conditioning off -premises station compressor control circuit's start -up and closes according to the return water temperature that the temperature measurement circuit detected. The utility model discloses it has following advantage to compare prior art: the utility model discloses an it realizes that self -checking function's air can central air conditioning machine to possess cybernetic loop pump detects return water temperature as single -chip control circuit and reaches the settlement temperature, the standby of central air conditioning off -premises station, and the circulating pump stop work, the circulating pump interval started five minutes in 5 to 30 minutes, detected the working medium temperature, played the electric energy effect of saving.
