Hot cold plate

I want a Peltier running on about 5V to both heat a cool a piece of Aluminium plate to provide one end at 40 degrees C and the other end 10 degrees C. The plate can be a C shape with Peltier at the open end or two plates separated by a Peltier at each end. The top plate will have a variable load placed on for heating small metal cylinders on. Needs to have minimal control but not exceed 45degrees C (maybe using PTC???)

I have attached a photo for clarification. This is two peltiers between 2 aluminium plates. One side has hot on top and the other has cold on top. This works but I am not sure about control. I want to be able to heat /cool four little metal jars spaced along the top plate so that they are about 40 / 30 / 20 / 10 °C. Important that the plate does not get hotter than 45°C

I also want the electronics very simple and foolproof. I can wire up a few mosfets and the like to test.
