Sundirect’s SC-Plus series is an upgraded version of the space heaters of the SC series. The major advantage of the Smart Infrared Space Heater is the control system. SC-Plus is equipped with a built-in thermostat receiver on the backside of the heater and can be wirelessly controlled with the Sundirect smart thermostats including Smart1.0, Smart1.0Pro, and SmartPlug. A bypass function of the SC-Plus models allows you to connect them to any kind of smart heating control system with no problem.
