Abstract

A water delivery device includes a body, a user interface, a micro-mixing valve, first and second capacitive sensors, and a controller. The body includes a base and a spout. The user interface is provided on the spout. The micro-mixing valve is contained within the body and is in fluid communication with a hot water source and a cold water source. The first capacitive sensor is provided below the user interface. The second capacitive sensor is provided below the user interface and is spaced apart from the first capacitive sensor. The controller is operatively connected to the first capacitive sensor, the second capacitive sensor, and the micro-mixing valve. Each of the first and second capacitive sensors is configured to be independently activated by a user to transmit a signal to the controller to increase or decrease a temperature of a flow of water flowing from the micro-mixing valve.
