Electronic pellet burner controller – NPBC-V3C-1/ NPBC-V4C-1 Modulation. The shortest switch time interval could be the cycle between two feedings, which usually is 20-30 seconds. For such a short period of time, the temperature of the heating installation can't change significantly and it's impossible for a human to sense the swings between the power levels.
