SMS Thermostat 

The SMS thermostat can be added to the SMS single fan controller to provide automatic temperature control. It is simple to use. Just set the desired temperature on the thermostat dial and set the extractor fan to an idle speed. When the temperature in the grow room reaches the temperature set on the thermostat the extractor fan will automatically increase its speed to full until the desired temperature is reached. The speed of the fan will then drop back down.
