I was happy with my new Gree air conditioner temperature display. I thought so, I'm going to buy a cheap Chinese thermometer and put it in my old air conditioning! This served well, because it has a probe that can be tailored by the termostado.
The flaw is that the display has low angle of sight. This angle you can't see anything!
Also to place supported the Cabinet. The feed is of one AAA battery.
There's the thermometer working. It is made for refrigerators and air conditioners.
Look at my “adaptation” in my old and yellowed consul. As the thermometer stays on vent registers the same temperature that the termostado.
Too bad the angle of sight is bad, but it's a good product. I bought on DealExtreme. I leave the link to the product. Enjoy and look for other thermometers using the AllChinese tool from the site TudoVemdaChina:
