ABSTRACT:
A faucet having an infrared sensor-actuated adjustable valve for automatic control of the discharge of water in response to the user's hands being positioned below the discharge spout. The infrared sensor is activated to control a solenoid valve thereinside. A manual valve mechanism is also provided for effecting a discharge of water by manual control of a single-axis stem during periods when the sensor is inoperative. The temperature of the water discharge created by actuation of either the automatic valve or the manual valve is established by rotation of the stem.
