Good day my name is Jayson the inventor of the ALT timer. It is a 24 hour mechanical timer fitted with extra outlet for your electric fan. It is very useful energy saving device with alot of positive feedbacks I have sold to almost 100 units. At first I used it for my personal use but upon checking on the market there is nothing sold like it. The only aircon to fan timer in the market can only do 1 thing which is to set the AC for a specific time and after the time runout the electric fan will turn on. But in a closed room after an hour the room will get hot and you'll probably need to turn on the ac again, but with my invention it can do a loop settings for 24 hours with 30 mins interval. Meaning you can set the AC for 1 hour and after an hour the ac will turn off the electric fan will turn on for 30 mins then ac will turn on again then electric fan so on and so on for 24 hours. It wont harm your ac because the interval is 30 mins. I'm very sure if it will be out in the market for large scale it will be a great product or else I wouldn't waste time patenting my invention and i have saved alot on my electric bill and can greatly help reduce the consumption on our electric grid. Thank you.
