Product review (4 stars): Nice unit
I am using this as a control for several different applications and am finding there is a learning curve concerning the placement of the probe. It would be helpful if the users manual where to suggest probe placement given different control situations.  For example:

One of my applications is for controlling the environment temperature in a standard home range oven between 89-95 deg F, switching a common heating pad on & off for the "koji" culturing {part of the miso process}. I placed the probe directly into the pyrex tray holding the koji culture. Initially the scheme worked but overnight the temperature hit 109 deg. Probably the better placement for the probe would be in the general air space. Oh well the first space shots also fizzled.
