thermostat kit provides a robust and low cost ST solution microcontroller and AC switches to control refrigerators, freezers or fridge/freezer combinations. Basic, defrost, and air circulation versions are configurable in order to address the low end and medium end cooling appliances market. It allows the control of a single phase induction motor and a light bulb, and optionally, a defrost resistor and a fan, working on 220/240VRMS, 50/60Hz mains voltage. The thermostat kit is operational with 100/120V RMS 50/60Hz but the supply capacitor value must be modified. The connection between the PC and STM8S microcontroller, the MCU performing thermostat regulation, is achieved through a USB bus. As the STM8S is a low cost MCU without an embedded USB peripheral, an additional MCU STM32 has been used as a bridge between the PC and STM8S MCU, for demonstrative purposes only.
