T-4002-9009 Johnson Controls Thermostat

Overview

The Johnson Controls T-4002-9009 is a high-volume output, single-temperature pneumatic thermostat designed for industrial and commercial HVAC applications. This reverse-acting controller provides a proportional output air signal to modulate pneumatic devices, such as valves and damper actuators, in response to temperature fluctuations. It is specifically designed for horizontal mounting and features a Celsius temperature scale for precise environmental monitoring.

Features

• Reverse-acting operation that modulates controlled devices as space temperature changes
• High-volume air flow capacity of 400 SCIM for efficient system response
• Bi-metallic sensing element for durable and accurate temperature detection
• Two-pipe configuration compatible with standard pneumatic distribution systems
• Horizontal orientation suitable for installations with vertical height constraints
• Adjustable sensitivity settings to fine-tune control system performance
• Barbed fittings for secure connection to 5/32 inch O.D. tubing
