Abstract
A control board controls operation of a plurality of ventilation fans and generates a fault signal upon occurrence of a predetermined fault condition. The control board includes a control circuit in a circuit board, an interface connector connected to the control circuit and mounted to the circuit board, and control connectors connected to the circuit and mounted to the circuit board. The control connectors are configured to connect the control circuit to ventilation fans or other components to be controlled. The control connectors are connected to a fault detection device of the control circuit operable to generate a fault signal upon occurrence of a predetermined fault condition at the control connectors. The control circuit is configured to disable the fault detection device with respect to the fault condition from any control connector that is not connected to a ventilation fan or other component to be controlled, depending on a predetermined input state determinable by a signaling device that is connectable with a ventilation fan to one of the control connectors.
