A/C Temp Controller

Hello i would like to maintain my room temp at 78 degrees . is there any temp controller i can connect to my wall mounted a/c unit you recommend. i see alot of day night temp controllers on bghydro.com but they say their for vent fans.. can these be used connected to a a/c unit? Thanks

I found one at walmart for around 25 canadian. It was made by woods and is pretty good, you can set it on heating or cooling then set the temp you want so it works with a/c or a heater. Check it out
