Again, Zoomed is not known for their thermostats or thermostat quality. It's an afterthought product for them and should only be used until you can get a proper thermostat from someone like Spyder Robotics - I put links to their herpstat products in my original post.
Here is a link to the probe placement manual for the herpstatez2. It clearly states what we've all been saying about probe placement and contradicts the instructions you have.
