EL-500 Cooling Thermostat 

The EL-500 Cooling Thermostat has a gas filled coil for impressive reliability. The air temperature accuracy is +/- 2 degrees. 

It's easy to use! Simply plug in the pre-wired cooling thermostat and plug in your exhaust fan into the integrated plug receptacle.

Set the dial to your desired temperature and you're ready to grow.

The EL-500 Cooling Thermostat will turn your fan ON when the temperature has reached 4 degrees above your chosen set point and then turns it OFF at 3 degrees below the set point.

Adjustable from 40 to 110 degrees. This thermostat is not water-tight so keep it away from the reservoir. UL Listed.
