A flow control apparatus including a housing having an enclosure and a lid being hingedly attached to the enclosure so as to cover the top of the enclosure. A device is positioned away from the housing and has a pair of operating states, e.g., open and closed for a valve. A CPU is positioned within the enclosure and is adapted to toggle the remote device between its operating states. A sensor is connected to a system, of which the remote device forms a part, for conveying to the CPU information about an operating characteristic of the system. A keypad is mounted atop the enclosure for inputting the preferred operating parameters of the system into the CPU. A display is also mounted atop the enclosure for visually confirming the operating parameters of the system input into the CPU. A solar panel is mounted atop the lid for powering the apparatus. In response to receiving information from the sensor, the CPU determines whether the operating characteristic described by the information falls within the preferred operating parameters input into the CPU and, if not, the CPU toggles the device from one operating state to the other.
