Ben instead of using a motor etc to control the temp. Try using a temp sensor and have the relay close the connection making the furnace or AC come on. Since the thermostat uses a coil with mercury to close the connection. You could have it done electrically. So it might take 2 relays since there are two connections that need to be closed. Fan and Cooling System. Here is a wire diagram: http://www.electrical-online.com/wp-content/uploads/2011/04/Thermostat-heat-cool-fan-on.jpg

  • I have a portable airconditioner unit that i wanted to control for my bedroom.

    It had a remote so I looked around for some code templates and found a simple IR libary for the arudino so i had it learn the basic commands for the aircon unit. Once i had the codes I used them in the arduino and an IR LED to transmit the codes when needed to the unit. I put a webserver on the unit and made an android app using App inventor to control the unit.

    This is the end result of the little project

    Its alot of bad code but it worked in the end.

    I have a heating unit for the house thats got a digital pannel but when you pull the digital pannel off the wall theres only 2 pins going to the outside heating unit. From what I was able to find all you do is join them together and the unit turns on. I have a plan to put an arduino infront of this to control it and a relay but have not had time for the project yet.
