Microcomputer controller with multiple installation and regulation and control modes for electric water heater

The utility model discloses a microcomputer controller with multiple installation and regulation and control modes for electric water heater, comprising an electric room box and a control display device. The electric room box and the control display device is connected into an integration by the interface of a signal wire pipe. The inside of the electric room box is provided with the microprocessor main board of a computer board; the microprocessor main board is not only installed a temperature-sensing probe and an actuator, but also the signal connection wire of the microprocessor main board is hidden in a signal wire storehouse in the electric room box; the other end of the microprocessor main board and the control display device can be connected into a system. The control display device not only can be installed on a water heater casing, but also the control display device can be removed down and the signal connection wire can be pulled out to make the control display device be moved and installed on the wall for conducting the connecting wire control for the water heater. The control display device is not only provided with a control display screen, a transparent cover and a regulation and control key, but also the control display device is provided with an arc curved face seat coinciding with the attaching face shape of the water heater, so that when the arc curved face seat is rotated to present the 90 degrees, the control display device horizontally installed on the horizontal electrical water heater in origin can be changed into the control display device uprightly installed on the casing of the upright electrical water heater; therefore the purpose that one machine is provided with multiple installation and the regulation and control modes can be reached.
