How to Setup and Operate
First connect the heater load (10 amps or less) to the load receptacle on the rear panel. Next plug the
control line cord into the appropriate 3-wire grounded power receptacle.
Toggle the lighted power switch to the “ON” position to apply power to the controller. Turn the control
knob to the desired setting. As the knob setting is increased, voltage to the load increases. Full line
voltage is applied at a dial setting of 100 percent. Settings below 100 percent are not linear. Verify
voltage prior to operation if necessary.
Manual power controls require experimentation to achieve the desired control setting for a
particular application. The PowrTrol offers precise repeatability once desired setting has been
determined for that application.
