Hello Anyone try this with their Enviro EF-2, EF-3, Napoleon NPS40, Harman, or Travis Lopi or Avalon AGP pellet stove or older model stove with a knob control for their distribution blower? Alot can be said for these old dial controls. They are simple to fix, easy to use and last along time because they are not easily suseptable to power surges. However when using potentiometers in an older electronic component circuit instead of triacs, you do loose some peak voltage to the blower and there is a higher current draw due to the greater electrical resistance of the pot. This means more watts and more money in electricity. This explains why Triacs are used in newer control panels. They can be biased with low voltage and switch the high 120 vac with no losses. This voltage and current meter display shows proof of the above statements. Note: The non linearity of the voltages vs the knob setting. Typical with potentiometers. That is whay they had pots with what they called Audio Taper. LOL Pics below show convection blower voltages for different settings. Pic 1 - MAX room blower setting. Pic 2 - Guage shows 96 volts drawing 22.5 amps Pic 3 - MIN room blower setting Pic 4 - Guage shows 33 volts drawing 2.2 amps Pic 5 - 1/2 room blower setting Pic 6 - Guage shows 38 volts drawing 3.8 amps Pic 7 - 3/4 room blower setting Pic 8 - Guage shows 44 volts drawing 4.7 amps Pic 9 - The fire!
