A fan-control device for overriding normal operation of a circulation fan delivering conditioned air through ductwork in an unconditioned space. The fan-control device includes a detection circuit and a fan relay. The detection circuit is configured to detect a cooling system control voltage and a cooling system control current and to output a fan control override signal when the cooling system control voltage is detected and the cooling system control current is absent.
