A thermostat is a component of a control system that will senses the temperature of asystem and it will
maintain the temperature below the maximum point. Thermostat maintains the temperature by switching
between heating or cooling devices on or off, or regulating the flow of a heat transfer fluid as needed, to
maintain the correct temperature. The thermostat system which designed by Xpedition software comprises
more of circuit complexity and the board size is also large. So we has planned to reduce the complexity
and size of the board so that we planned to design thermostat system in Xpedition. The TDIM FRAM
thermostat reference design, featuring the MSP430FR4XX FRAM based ultra-low power microcontroller,
is a fully functioning battery powered platform for the thermostat that allows user to evaluate the
MSP430FR4XX device in thermostat application the most popular thermostat is the digital electronic
thermostat. This kind of thermostat has thermistors or other semiconductor temperature sensors to
measure temperature. All hardware and software are available for developers to easily develop their own
thermostat application
