Digital Thermostat with LED Temperature Display

I needed to replace two old, unreliable thermostats for controlling the heating and cooling for a large garden shed.
Commercial basic digital thermostats are available quite cheaply, but some lack the ability to control heavy loads or have the extra features that I require for saving energy when the door is often left open or to indicate temperature being out of range etc.

I like the PIC18F1320 microcontroller used in my previous project – so decided to use it again in a very similar design to drive three multiplexed LED displays and read the temperature from a Dallas/Maxim DS18x20 “1-Wire” digital sensor.

Demo-application for Philips LPC2000 ARM7TDMI controller with a KS0108/KS0107-based graphics-LCD (128*64 pixels), DCF77 time-receiver and Onewire-Bus (for DS18×20-Temp.-Sensor).The time and date are received with a DCF77-receiver-module .The DCF77-signal is transmitted from a station near Frankfurt/Main, Germany and can be received all over Europe, North Africa and the Middle-East.
