摘要: A method of determining and controlling a load by a controller. The method comprises the steps of transmitting a signal for a first predetermined time period on an electrical line having a load in parallel with a capacitor; monitoring the electrical line for electrical activity within a second predetermined time period following the first time period; and controlling the load in response to the presence or absence of the electrical activity.
