1st stage: inside fan only
2nd stage: inside fan plus peltier and outside fan
In 1st stage the energy consumption would be very low, just the inside fan. The 70 watt peltier will only be used when 2nd stage will be active.
I'm skeptical that the Peltier device is going to make any significant difference in cooling. When you need it the most (it's hot out), it will help the least. 70W is pretty small, a 70W peltier cooler will yield around 200 BTU/Hr of cooling, or around 1.5% of a typical 13,500 BTU RV air conditioner.
