The presented device is an advance thermostat based on Atmel microcontroller — Atmega8. The most important features are:
- 5 independent high power outputs,
- 5 independent temperature measuring channels,
- LCD display.
The device can operate in one of two modes — automatic and manual. Moreover, each temperature channel can be assigned to any high power output. It ensures high flexibility of the solution and easy modification of the system.
The user interface is intuitive and all operation parameters can be modified through it. All the parameters are stored in EEPROM memory. In case of power failure the parameters are restored and the device can operate.
