HydroGuard 447 Piezo

Utilizes Piezo sensor technology, activated by a bather depressing a pushbutton. When the pushbutton invades the proximity sensor field, the sensor sends a signal to the control box, which then signals the solenoid to open and send water to the showerhead. The shower will continue to operate to the maximum shower time, or until the bather depresses the pushbutton again, signaling the end of the shower. The sensor assembly and solenoid connects to a modular control box, of rugged polycarbonate, which is easily mounted behind the wall or in the ceiling. The control box features a unique, easily adjusted potentiometer for quick adjustment of maximum run time from 0 to approximately 7 minutes. The shower system also features a rugged non metallic solenoid assembly with a straight through flow path, allowing a wider flow range than most other solenoid valves. In addition, the solenoid is slow closing to minimize the chance of water hammer. All components feature unique modular jack connections, similar to those found on your telephone, to make installation a virtual snap. All showers are supplied complete with the proximity sensor assembly, pushbutton assembly, 24VAC transformer (plug in or box, as specified), 24 volt AC solenoid valve, control box and appropriate mounting hardware.
