This would be your plug and play model, or as close as you can get. The outlet box will need a female outlet added.

3 step installation
1) Mount the plastic enclosure containing the controller to the outside of your smokehouse (about eye level).
2) Drill small hole thru wall of smokehouse directly below the controller enclosure and route the sensor and sensor wire thru hole Mount sensor to the inside wall with mounting blocks provided.
3) Mount the smaller rectangle duplex box to outside of smokehouse below the controller box and route wires to your to your burner, hotplate, solenoid, gas valve or blower motor. You may install an outlet in this duplex box enabling you to plug a hot plate directly into the duplex box.

This is not a PID controller. You can have temperature swing. However, if it is like the TS model I put together then you can control the swings by reducing the power to the heating element via the slide bar rheostat control on the Bradley.
If you go this route then what I suggest is getting your box as close to the target temperature without the controller plugged in--with the food in the box. Once there plug the controller into the generator. Set the temperature you want on the controller and then plug the heating element into the controller.
By doing it this way your rheostat will be set to the temperature you want, your box will be balanced and as the ambient air temperature changes, or the moisture level lowers in the box the controller will come into play. Do not set your rheostat to the far right (highest power setting) or the box temperature could swing as much as 15 F plus degrees.
Good luck with your choice.
