Is it possible to wire a wall thermastat, used for central heating and air conditioing to a window air conditioner that has an exsisting adjustable thermastat?

Please don't answer if you don't understand my question!!

For 120 volt, would need transformer(120 volt)to whatever relay or contactor you have that the contacts will handle the current. Line voltage in to contactor, AC goes to load side.
On/Off switch. Would not cut cord on AC, Would have receptacle on load side.
240 volts needs 2 poles, and 240 volt transformer.

I think Stratmando was trying to describe how you would build a device that would allow a standard wall thermostat to drive a 120V (or 240V) power supply for the AC unit. This device would have to have a relay that allows the low voltage thermostate wiring to control power to the AC iunit. You would plug the AC into this device, and the thermostat would control when power is applied to the AC - a basic on/off switch for the AC unit.

The point is that as far as I know there are no window units that are built with standard external connections for a wall thermostat connection, so you're going to have to build the interface yourself. You asked if it was possible - he gave you the bare bones outline of how to do it.

And please tone down the rhetoric here - he obviously could have written a more coherent reply, but don't assume that just because you don't understand his answer that he doesn't understand your question.

The whole world is full of ameteur electricians is that toned down enuf fr u dumbfuk

He Ebaines, Thanks, You didn't deserve that. I was almost going to suggest smoke or heat detector shutoff, or a delay on module, to keep compressor from kicking back on in short period.
Take Care, Respect your advice.
Paul, You have 4 post, same question, take first response to Qualified electrician, or a helper, they will make sense of that.

You can use what is called a line voltage tsatat. You can cut one leg of the power cord a loop it through the tstat.what this would do is allow power when the tstat call for cooler temp. You would have to leave your installed switches set to the on and as low as the tstat on your air unit will go so when the line tstat called for power it would close and allow the unit to run. You can get one for 110 or 220 which ever you need. I don't know if this is what you wanted to know or if your already had a normal tstat for a central unit and just wanted to use that

[Stratmando]

Finnally you proved you do not know what you were asking. You asked "Central Air Thermostat". He said, "Line Voltage TStat"?

Good advice from above, Paul, cut your cord. Maybe unplug first.

Simple, door bell transformer, 28volt relay* , deep 4x4" junction box w/ strain relief, outlet*, outlet cover, plug*, wire nuts, wire*. If you can not figure the rest for yourself DON"T DO IT!
