I have played with the new thermoelectric controller and will carefully wire it up tomorrow. It is a microprocessor controlled integral and differential controller. What that means by adjusting the parameters it will quickly go down to the set temperature and hold it there without any oscillation. Why reinvent the wheel when it has been done by experts.
