## Description

Amtrak Solar 12V Thermostat – Automatic Inline Temperature Controller for Solar Attic Fan – Plug-and-Play Thermal Switch for Roof Vent, Gable Vent, Shed, Garage, Greenhouse & RV – Made in USA - desertcart.com

Review: Great thermostat - Works great for my solar powered fan for my greenhouse. Plug in and works like a champ. Works as expected.
Review: Works as advertised! - We bought the house from the original owner, who had had a solar powered fan installed in an east-facing gable. So as soon as the sun came up, fan powered on. Typically, it's not hot enough to justify usage first thing in the morning. The problem is the house is turned slightly off compass axis, so that by late afternoon, it's not gaining charge and the fan drops out. The install for the thermostat is bone simple. It was working yesterday afternoon while the attic temperature was above 85 degrees. It's cool this morning, and the fan is off, building charge in the battery. Outstanding...

## Questions & Answers

**Q: Thermostat doesn't turn off, temp well below 85F. Fan center is about 5 feet, thermostat mounted near bottom of the fan, off to the side a bit.**
A: it happened to me too, the thermostats they are providing, are defective, or wrong for the product

**Q: Will this work with a non amtrak solar pannel as the power source?**
A: Yes, If the panel has 16/14 gauge bullet connectors. If the panel has the MC4 Connectors the tip of the female connector will need to be trimmed down and might need to be wiggled and pushed a little but it will work.

**Q: Shipping $54? Why?**
A: We have free shipping. Just checked to see if there was an error and it shows up as free shipping.

**Q: What is the voltage / current rating for the switch?**
A: Can be used for any attic fan, not just solar powered, with system voltages between 0 and 250 volts and up to 10 amps of current
