Abstract
An electronic device is disclosed for controlling the temperature of a liquid such as water flowing into a container such as a bathtub or the like. The device also controls the level of liquid within the container and includes a solid state circuit in conjunction with a temperature sensing device for maintaining the temperature of the liquid within the container to a preselected level. The control device includes a plurality of switches for preselecting the required temperature and liquid level. Switches are also provided for selecting the use of the bathtub as a bath or as a shower. The flow and mixing of water into the bathtub and the flow of water out of the bathtub is accomplished by solenoid flow control valves responsive to the control device. The invention may be applied to industrial, commercial, medical or residential applications and the like.
