T-5502-1002 Johnson Controls Thermostat

Overview

The Johnson Controls T-5502-1002 is a pneumatic temperature indicator designed to provide continuous visual indication of temperatures in commercial HVAC and building automation environments. It operates completely on pneumatic pressure without requiring electrical power, making it highly reliable for areas where running electrical connections is impractical.

Features

• Continuous visual temperature indication driven entirely by a compressed air signal.
• No electrical power required, offering maintenance-free and intrinsically safe operation.
• Dual-scale dial displaying both Fahrenheit and metric ranges for convenient reading.
• Clear plastic protective lens that easily screws off for cleaning and access to the recalibration screw.
• Versatile mounting styles supporting either flush or surface installations on panels or walls.
