PURPOSE:To execute a high load and high efficiency operation which has concentrated a load, even if a temperature characteristic, etc. of each load to which compressed gas is supplied from one compressor are different from each other, by providing each specific timer, a detecting device, etc. CONSTITUTION:Solenoid valves SV1-SV3 are opened and closed by the respective thermostats TH1-TH3. The opening and closing states of the thermostats TH1-TH3 are supplied to logical circuits 18, 21 and 41 through an inputting circuit 13, and a detecting device 36 for detecting the period before all the thermostats TH1-TH3 are turned off once after the time point when a compressor 5 has been restarted by the second timer 43. While this detecting device 36 is detecting said period, the opening and closing control is executed by only the thermostats TH1-TH3. Also, the second timer 43 restarts the compressor 5, and after that, control which has used the first timer, too is responed. |
