Pros & Cons

The AI used to provide these results are constantly improving. These results might change.

Pros

The speed rheostat works perfectly and replaced a 22-year old controller that just quit working one day. Used to vary the speed of a fireplace fan. Used this to control a 6amp whole house fan.

Overall, pleased with the purchase. Works like a charm! No issues at all - works as advertised.

The exterior plate of the switch juts out from the wall about 7/8 (seven eighths of an inch) the switch works exactly as described. Has an insulated plate that cannot be removed. Attached this with a magnetic heat sensor in line and works perfectly.



Cons

I'm not sure if i received a defective unit.

Quality


It was not a big problem and i was expecting that to be the case based on other comments on the product


Based on build quality and tech support experience i have to give this product five stars


Id give it three stars if it was based on my overall happiness with the device but one cannot change the laws of physics

Competitiveness


I installed this along with a maxxair if18 exhaust fan


Using it to control a broan 900 cfm ventilation fan

    It made the fan run with a very loud whining noise


    Posted by a reviewer on Amazon

    Tech support for kb electronics was knowledgeable but could not determine why the noise was present


    Posted by a reviewer on Amazon

    After a reasonable amount of searching and reading i learned that most triac based speed controls cause motors to whine


    Posted by a reviewer on Amazon

    The reason is physics based and i am not an engineer so i only understood on a very rudimentary level


    Posted by a reviewer on Amazon

    According to the article i found it is shown that the oddtime harmonic voltages introduced by the controller produce pulsating torques at all even multiples of the supply frequency and that the extra noise components occur at these frequencies


    Posted by a reviewer on Amazon

    Anyway long story short this device will possibly make your motor emit a whining sound


    Posted by a reviewer on Amazon

    Aggravating but that is the nature of this device


    Posted by a reviewer on Amazon

    I cant fault the manufacturer or the device any stars for being inherently noisy
