The present invention provides a ventilation system capable of varying the capacities of an air supply fan and an exhaust fan after installation. Drive circuits (31, 32) for driving the air supply fan (24) and the exhaust fan (25), respectively, are connected to a control part (3). Each of the drive circuits (31, 32) is provided with a tap for switching the blowing capacity of the air supply fan (24) and the blowing capacity of the exhaust fan (25), respectively, into a plurality of levels. Additionally, a remote control receiver (33) is connected to the control part (3) so that signals for setting the operation mode of this ventilation system, which are outputted from a remote control transmitter (34), are inputted into the remote control receiver (33). The control part (3) switches the tap provided in each of the drive circuits (31, 32) according to the signals inputted from the remote control receiver (33), thereby driving the air supply fan (24) and the exhaust fan (25) at each capacity set by the user. <IMAGE> |
