Review on Johnson Controls A421ABC 04C Line Voltage Temperature by Sean Garrison

Revainrating 5 out of 5

Excellent control. Very diverse.

I have been using this type of Johnson controller for many years. They have always offered great flexibility for an almost infinite range of temperature applications. Highly recommended.

Pros
  • Temperature and Humidity
Cons
  • No Instructions
