Sentinel - Cool/Heat Thermo THERM-1 (702512)

The Sentinel THERM-1 allows you to affordably control the temperature within your growing environment. The THERM-1 can be set to either heat or cool. Just connect your equipment, then set the temperature that you wish to maintain. If the temperature varies from your setting, the receptacle is activated. When not in use, the spring loaded cover closes the receptacle, keeping moisture and dust from entering the unit. The temperature differential is fixed at 3.5 degrees. Comes with a 2 meter (6 foot)  remote waterproof thermistor sensor. The THERM-1 is rated for 15 amps @ 120 volts.
