Abstract
A heat-exchange ventilation device includes: a heater connection terminal to which an external connection heater is connected; a temperature sensor that measures a temperature of a supply air flow passing through an air supply passage; and a control unit that controls operations of an air supply fan and an air exhaust fan and turning-on and turning-off of the external connection heater based on a measurement result of the temperature sensor. The external connection heater is installed in an outdoor air-supply duct and heats a supply air flow flowing through the air supply passage into a heat exchanger. The air supply fan is operable at a plurality of intensities, and the control unit prohibits a state in which the air supply fan is operated at an intensity lower than an intensity set in advance and the external connection heater is turned on.
