Infratech offers a variety of control options for maximum energy efficiency, control versatility, ease of use and affordability. Not to be confused with a dimmer, the INF input regulator gently cycles the heater on/off at regular intervals when your heater is not on full power. Ideal for controlling single element heaters of up to 3000 watts such as the W-Series and Slimline Series, this 240V unit is a switch only, the gang box is not included. Other Infratech control options include simple on/off switches for all models and a duplex switch option for the dual element WD-Series. Please note that a licensed electrician is required to verify voltage and available amperage.
