Very happy with product

Same physical size as my old one making mounting easier. Wiring connections were heavy duty and internal wiring bigger than my old... switch. Contactors are heavy duty. All in all, a well built unit. I also like the generator dominate feature, which allows overriding the post power during brownouts or park low voltage without having to go outside to unplug the post especially during rain.

Pros: Solid casing, Heavy wire

Will this switch automaticlly start the gen. when the thermostat calls for cool.

by Anonymous – May 29, 2015

Answer the Question

No. When the generator is started, incoming electrical priority goes to generator as opposed to shore power, this transfer switch only changes from one source power to another. As to if the generator will start automatically due to the thermostat, that would depend on the wiring/thermostat programming in your RV. You may want to consult with your RV manufacturer.
