Product Overview

  • Fogco DC Thermostat Kit: Smart, Automated Control for Your Solar Ventilation System

Unlock the full potential of your solar-powered ventilation with the Fogco DC Thermostat Kit. Designed for simplicity and efficiency, this essential accessory allows you to automate the operation of your Fogco DC Snap-Fan, ensuring it runs only when needed. Perfect for DIY homeowners, agricultural professionals, and off-grid enthusiasts, this thermostat kit helps you maintain ideal temperatures in your greenhouse, attic, barn, or workshop while maximizing energy savings.

Set It and Forget It: Automated Temperature Management

Take the guesswork out of managing your environment. The Fogco DC Thermostat Kit allows you to set a desired temperature, and the system does the rest. When the ambient temperature rises above your set point, the thermostat activates your DC fan, providing crucial airflow and cooling. Once the temperature drops to the optimal level, it automatically powers the fan down. This simple yet effective automation is a game-changer for applications where temperature regulation is key.

Key features include:

  • Simple Mechanical Control: Easily set your desired temperature with a straightforward dial. The thermostat features a 4-degree Fahrenheit differential to prevent rapid on-and-off cycling.
  • Manual On/Off Switch: The thermostat also functions as a convenient in-line on/off switch, giving you full manual control over your fan's operation whenever you need it.

Plug-and-Play Installation for Solar Direct Systems

Engineered for seamless integration, the DC Thermostat Kit is incredibly easy to install. It comes equipped with 10 feet of durable cable and industry-standard MC4 connectors, allowing you to place it directly in-line between your solar panel and your DC Snap-Fan. This plug-and-play design means no complicated wiring or electrical work is required, making it an ideal upgrade for DIY solar projects. It's the simplest way to add smart control to your solar ventilation system.

The Perfect Companion for Fogco DC Snap-Fans

This thermostat is specifically designed to work flawlessly with Fogco's line of high-efficiency Brushless DC Snap-Fans, including the 12", 16", 20", 24", and 28" models.

Versatile Applications for Smart Cooling

The Fogco DC Thermostat Kit is an indispensable tool for a wide variety of environments:

  • Greenhouses & High Tunnels: Protect plants from overheating by automatically activating exhaust fans when the sun is out but temperatures are high. On cool, sunny days, it keeps the fan off to retain warmth. [2]
  • Attics & Crawlspaces: Reduce your home's cooling load by ensuring your solar attic fan only runs during the hottest parts of the day, efficiently removing trapped heat.
  • Barns & Agricultural Buildings: Maintain comfortable temperatures for livestock or stored goods without wasting energy.
  • Off-Grid Cabins & Tiny Homes: Automate your ventilation for improved air quality and comfort, conserving power for other essential uses.
  • Sheds, Garages & Workshops: Keep your workspace cool and comfortable automatically, so it's ready for you whenever you need it.

Frequently Asked Questions

Is this thermostat compatible with any DC fan?+
While designed specifically for Fogco DC Snap-Fans (12" to 28" models), it can work with most brushless DC fans that utilize MC4 connectors, provided the voltage and current ratings of the thermostat are not exceeded.
Does this require a battery or external power source?+
No, this is a passive mechanical thermostat designed for solar-direct systems. It installs in-line between your solar panel and the fan, using the solar energy to operate the circuit when the temperature threshold is met.
How does the 4-degree differential work?+
The 4-degree Fahrenheit differential prevents 'short-cycling.' For example, if set to 80°F, the fan will turn on at 80°F and continue running until the temperature drops to 76°F, protecting your fan motor from rapid starting and stopping.
