ABSTRACT:
The electrical energy flowing between a power source and a furnace blower motor is sensed for controlling the operation of a humidifier. A removable current sensor is connected without damaging or disfiguring the connecting lead being sensed. A solid state switch operatively connects the humidifier to a power source in response to the sensed current and is electrically isolated from the current sensor. The control circuit provides a time delay in the energization and the de-energization of the humidifier and is responsive to the current flow in the sensed lead.
