Programmable Thermoregulator Design

The aim of the study was to design, build and experimentally verify a programmable thermostat. The main control unit of the thermostat is an ATmega168 microcontroller which communicates via I2C bus with remote MAX6615 chips. They are used to measure temperature with a set of thermistors and control the flow of the hot water in the heating system. This work deals with issues of remote control through the I2C bus, servomotor steering, precision temperature measurement and describes the inner workings of the system. The next chapter includes a proposal for possible extension of the system. The last part contains the manual of the control menu structure and a brief description of the software
