The SMSCOM SPC is a heavy duty 7amp twin fan controller that automatically adjusts the speed of both an inlet and exhaust fan to maintain a set temperature and optimum air pressure inside the room. The SPC will automatically calculate the exact running speed for your fans to maintain the temperature you set. The highest and lowest speeds the fans can work between are user controllable.
