A/C question

[ftpiercecracker1]

I'm the process of stripping down all electrical in my truck to the bare minimum, save a few Creature Comforts such as the A/C.

 

But I want to know if and why this is neccessary for the A/C to function.

 

I understand this is the thermostat/rheostat? for the A/C, but why does it need this? I figured the AC simply operates off the hi/low pressure switch on the dryer. Why does it need this. Does it need this? Can I delete it without negatively affecting A/C performance?

So I realized there's some writing on the back of this device I took a picture of it.

 

It seems the job of this device is to step in and force the AC compressor to engage in order to maintain a set air temperature, hence the two adjustment screws, regardless of line pressure.

 

 

 

This makes me curious, could I potentially put in a potentiometer in place of this device and a have adjustable climate control? 

 

Nevermind that would not work, because this device controls two aspects of the compressor cut in and cut out.

 

A single point of adjustment would mean the compressor would be constantly kicking on and off trying to maintain a very specific pressure.

If it's what I think it is its to keep the unit from freezing, it senses the temp and cuts the power to the clutch. But I could be wrong been a while since I studied a/c.

Ah, ok that makes sense.
