Hi, im starting a marine aquarium and cant afford a chiller for it, i have thought of wiring a simple thermister to the aircon remote's power button, i want to have the thermostat's probe in the aquarium water and have it connected to the On/Off button on the remote, i want the aircon to come on when the temp in the tank gets too high and when the correct temp is reached the aircon shuts off. i'm not a complete noob, i have some experience with building simple circuits and whatnot, but have never tried designing something on my own, i wouldnt know where to start. If someone can point me in a good direction, or thay know of a similar circuit that can do what im trying to do, please share
Thanks.
