Abstract

PURPOSE: To control room temperature and ventilation by automatically selecting the operation mode of the ventilator by means of a timer circuit, two switch units and a device energized by a drive signal.
CONSTITUTION: The operational amplifier 17 is so set that when VP>VN (VP: potential of the +input terminal; VN: potential of the -input terminal), the potential of the output terminal 29 of said amplifier will be of a high level, or substantially same as the potential of the DC bus 9, and when VP<VN, it will take a low level, or substantially same as the potential of the common bus 3. The operating switch 4 is arranged at a sequential position, and when the contact pieces a and d are set ON, a voltage is applied to the DC bus 9 to maintain the timing condenser 18 in a non-charged state. When the contact pieces a and d are set OFF in a condition where the ventilating fan 12 is in continuous operation, the timer circuit 16 is actuated from this time point and the operation of the fan 12 stops upon passage of a set period of time.
