Written If you need to start and stop your air conditioner just because your remote is broken,  then you already have got an answer from Uzair Sharf,  but keep in mind that you can buy a replacement universal remote for just a few bucks. Apart from this,  the only other reason i can think for someone needing to avoid the remote control, is to deny direct access to the air conditioner to the room user (start and stop the air conditioner in a hotel for example, if you want it to work in a fixed temperature without giving the customer the ability to change it)If this is what you want to do, then you could use a wi-fi remote unit like this one herehttp://www.aenaos-sa.gr/airpatro... which will give you full control on your air conditioner from your mobile phone (start and stop your air conditioner, adjust fan speed and adjust the louver). (the website is in greek, so you will have to use auto-translation or have a look at the video).Written There can be two possibilities either you don't have a remote and want to switch on AC manually or you want this whole thing to get automated.lets suppose you don't have a remote, well for this Uzair Sharf , go through his answer, has correctly mentioned in his answer about how to get your AC on manually.

And if you want to get this thing automated, you need to spend some extra bucks. Get one thermistor fixed on one of the wall of your room. Now form a loop of power circuit, consisting thermistor in between and set a temperature limit at which you want the AC to get in.This can be done by an electrician if you supply the switches, thermistor etc.Written Make and model of any particular appliance is absolutely necessary.  Personally I have never even seen an AC unit with a remote control, think that is a horrendous idea, and would never ever want one.  But there has to be a manual control as well.  I find it absurd that they would not put a power on/off on the front of any AC using, as that is a violation of safety standards.  But there has to be one somewhere, even if you have to take part of the front cover off.  I would suggest that they are universal remotes available also, except that I find remote control for something like AC to be too absurd to even consider.  That is like having a remote control to flush your toilet or something.
