Customer Reviews


Rated 2 out of 5 by 1reviewer.
Rated 2 out of 5 by I have been in the pneumatic field for over 30 years & that's all I do. Does that make me an expert? No, but it gives me experience to pass on. Johnson Control thermostats as of recent have become more difficult to operate; the indicator wheel needs to have a pair of pliers to turn. The allen head screws used for attaching stat to base & cover to stat are extremely difficult to turn. September 30, 2013
