Hi folks,

So, even though the envirocoolers work great, it appears that the parent company was a little misleading on their literature. I have not found a way to make them warm, and there does not appear to be a way to adjust the temperature. Break/If there is and I am just too dumb, please post the instructions/

That said, the unit obviously has a temperature sensor and it seems like it would be somewhat simple to add in a rheostat to allow for temperature control. I am pretty handy with a soldering iron but I would probably break 2-3 units before I got it right via trial and error. Is anybody here a bit more electrically savvy? I am happy to pull my control board out and take pics but I am not sure I can figure out what to take out and what to add. I'd like to be able to use it as a freezer, but for the price I am tickled pink to have it as is.

Any thoughts?

I don't have one but, I am guessing these are the 2 statements that are important to note.

Holds temperatures at 4 degrees C +/-2 degrees
Heats and cools making it the ideal year round solution

I think the heat part might only come into play when it is colder then 2 degrees C outside. just a thought.
 
I have one and I have also wondered about controlling the temperature since it did not come with a manual and I haven't been able to find one on the internet. My impression is that these were designed as medical transport units for transporting medical supplies and devices that required a steady, constant temperature, hence the 3 year duty cycle. I'm not sure they were built to be a freezer or a warmer but I'm the first to admit that I could be wrong. I'd love to have those features but I love the fact that mine just sits in the back of the truck and runs constantly making little noise and requiring very little power to do so.
 
I don't have a spare one, but I'm willing to contribute some cash to purchasing some to test it out.
 
Not sure that the technology used allows a lot of adjustability. I don't know a lot about Piston Sterling motors, but I would guess that whoever took on this task would have to do some research into them before any adjustment is made...

Excellent point. It hadn't really occurred to me that one might need to transfer temperature controlled medical supplies into extremely cold areas.

Free Piston Stirling Cooler: About FPSC

That link is from the manufacturer. It appears that the technology is more than capable of accommodating a variable temperature control--one of their products under "portable cooler box" has five temp settings--I am assuming that each button simply changes the input voltage to the PCB.
 
I am wrong.
