STEVAL-IHT001V2

Cold thermostat kit based on AC switches and the STM8S
  • active 活性

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 VRMS, 50/60 Hz mains 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.

Data Brief

Key Features

  • Low-cost solution for spark-free thermostats:
  • No need for a sealed version
  • Low-cost STM8S microcontroller for thermostat control
  • Low-cost capacitive power supply
  • High efficiency:
  • Refrigerator consumption reduction by adjusting and reducing the hysteresis threshold of the temperature
  • Improved efficiency by turning on the defrost resistor only when it's useful and not at each OFF cycle of the compressor (as done in some mechanical thermostats)
  • High system immunity:
  • Overvoltage protected ACS switches: ACST610-8FP for compressor control, ACS110-7SN for defrost resistor and ACS102-6TA for light bulb and fan
  • Class A criteria for IEC 61000-4-4 up to above 3 kV levels
  • Flexibility:
  • Development: program setting with PC interface to change firmware variables
  • Industrialization: end-of-production MCU programming thanks to FLASH, for soft upgrade and efficient MCU stock management
  • RoHS compliant
