Description

The STEVAL-IHT001V2 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 220/240 V

voltage. The thermostat kit is operational with

100/120 V RMS 50/60 Hz but the supply capacitor

value must be modified.

The board can operate in an ambient temperature

range from 0 °C to 60 °C.

The exact maximum temperature depends on the

power of the loads. For demonstrative purposes a

graphic user interface (GUI) has been developed.

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.
