New CoolBot controller out of the box, never been used. Ended up not needing this device. This device can turn any well insulated room/vehicle, etc... into a cooling unit. This device only needs connection to an air conditioner to complete installation. The idea behind this device is it tricks the air conditioner to act like a cooler unit to effectively store agricultural produce, or any other item that needs to keep cold. Very wide range of potential uses, even outside agricultural uses. This unit comes with a description that explains/recommends the best kinds of air conditioner units to pair up with it. Contact with me can be made through email. I am located near the Nanaimo Airport in northern Ladysmith.
