The invention provides a vehicle temperature control device and a method for controlling the vehicle temperature control device. A compressor provided in the first circuit and compressing the first heat medium; a sensor provided in the first circuit and measuring the temperature or pressure of the first heat medium; a second circuit in which a second heat medium flows; a heat exchanger that spans the first and second circuits and exchanges heat between the first and second heat mediums; the first circuit has a first loop in which a first heat medium circulates through the compressor and the heat exchanger. The second circuit has: a first line that passes through the heat exchanger; a second line that bypasses the heat exchanger; a valve that switches a line through which the second heat medium flows between the first line and the second line; and a second loop that circulates the second heat medium through either the first line or the second line. The control unit adjusts the duty ratio, which is the ratio of the time during which the second heat medium flows in the first line to a predetermined time, by means of the valve on the basis of the measured value of the sensor.
