I have this in my fermenting fridge, It supports up to 16A output. It is heating and cooling. Only PITA is it's programmable for different times each day. Nice if controling a house, a big PITA if wanting to adjust the temp because you have to adjust it for 3 time periods 6 times (5 weekdays and weekend), so you're setting the temp 18 times.
And the Probe is SUPER SHORT. But could possibly be replaced, I haven't tried. Held temps right at 65 the one time I've used it though.
I bought it at Menards for $30-$35
