Controlling Holding Plate systems

If you have an existing holding plate system here is a simple trick that will save you amp hours. The thermostat has a built in inefficiency due to "Hysterisis" ,check it out here.


Once the refrigerative load is known it makes more sense ( pun intended) to control the system with an event timer inserted in the control circuit. This allows you to also budget your amp hours and run the system when you are getting solar input. By doing so you will partially eliminate the waste of energy transfer through you battery bank. That is solar electric to chemical to electric to mechanical. You can also arrange that the compressor which might be right under your bunk not to switch itself on in the middle of the night and ruin a good nights sleep?

Beware of cheaper timers, I have recommended this brand for years and have never heard of problems.
