You’re working in the office right now, and will be back to home in couple of minutes. However, your home heating system is not properly warm up yet! You’re wondering, “It would be better, if I can control my home heating system from my working place!”

Guess what, your wish is granted!

Today, you’re having the opportunity to build an high end central heating programmer, which is equipped with serial computer interface. Believe it or not, this smart device will help you to save on the electricity bills, as it has the following incredible features:

• It includes an independent control for heating system and hot water.

• It has 10 flexible program entries.

• The programs can be easily set based on the working days.

• It equipped with manual advance for water and heating.

• Battery backup for Real Time Clock (RTC).

• RS232 serial interface with command line interface.

Basically, this device is built based on microchip PIC 16F628A microcontroller, and well-designed for controlling the domestic heating system. The device transfers the outputs via two relays to control the supply of heating and hot water. Since there are 10 program entries, hence each of them can control the heating and water independently!

In addition, you can switch the program entries, to weekdays, weekend or everyday.
