Here's a shot of the Love Controller. I put it in a project box along with the power outlet.

Below is a description of how I use this.

The controller is used to program the exact temp I want my strike water to be at when I wake up in the morning.

I have a heavy duty timer switch plugged into a GFCI outlet. I program the timer to switch on power to the Love Controller in the middle of the night. The controller takes a temp reading via the probe. If the water is colder than my set temp...the controller switches on power to the power outlet. The heat stick is plugged into the power outlet. Thus..the heat stick starts heating the water. I have an additional timer plugged into the same power outlet. I have this timer set to switch on power to the stir motor for 15 minutes on.......15 minutes off.....and so on.
