SMS Twin Fan Controller with Thermostat
SMS Twin fan controller. Unlike most other temperature controllers the SMS Twin controller and SPC temperature controller constantly samples air temperature and adjusts fan speed until the optimum fan speed for the set temperature is achieved. This avoids fans ramping up from pre idle speeds causing unnecessary noise and temperature fluctuations. Set the minimum input and output of speeds for your grow room extractor fans and the SMS Twin will increases the speed when triggered by the remote temperature sensor. Easy set up, plug and play Software controlled No fluctuations in temperature or fan noise. Controls temperature +/-1oC at desired temperature.
