## Description

Amtrak Solar Thermostat – Made in USA – Automatic 12V Inline Temperature Controller – Plug-and-Play On/Off Switch for Solar Attic Fan, Roof Vent, Gable, Shed, RV or Greenhouse Ventilation - desertcart.com

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...
Review: The thermostat works great. - The temperatures it works at is what they say. Very easy to hook up to their solar panel - fan setup. I would recommend the thermostat.

## Questions & Answers

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
