SMS Twin Fan Controller (7Amp/14Amp)

'Outstanding ventilation control'

The SMS Twin Controller automatically controls the running speed of your extractor and intake fan to ensure an optimum grow room temperature. They feature the same built-in processor as the SMS Smart Controller, which calculates the exact speed your fans need to run at in order to maintain the temperature you set. The two meter sensor probe constantly monitors the temperature of your grow room and increases/decreases fan speed, as required. This incremental method of fan speed adjustment provides highly accurate temperature control (accurate to +/- 1°C) and limits ventilation noise, when compared to other twin fan speed controllers that switch fans from their idle setting, straight onto full power. The SMS SPC Controllers will allow you to manually adjust both the minimum and maximum speed. This helps to optimise the ideal pressure inside your grow room, ensuring that air is not forced through additional openings and that any odour is contained within your carbon filter. The SMS SPC Controllers also have an adjustable temperature sensitivity control, which allows you to adjust the temperature range from the set-point where the fans operate between minimum and maximum fan speed.

Available with a maximum load of both 7Amp (£172.95) and 14Amp (£226.95)
