Johnson Controls T-4002-304 Conversion Kit
For facility managers and maintenance contractors overseeing legacy pneumatic systems, the Johnson Controls T-4002-304 Conversion Kit provides a dependable solution for two-pipe thermostat replacement. Designed for reverse acting (RA) operation, this kit is specifically engineered to replace non-Johnson Controls instruments, integrating a single temperature controller with a 55-85°F (13-29°C) dial range. The T-4002 unit utilizes a high-sensitivity bimetal sensing element and pneumatic feedback to deliver precise proportional air signal output, modulating valves and dampers with an operating pressure range of 13 to 25 PSIG.
This pneumatic room thermostat package includes a durable beige cover and a universal subplate designed for both horizontal and vertical mounting. The comprehensive kit simplifies HVAC pneumatic control upgrades by providing 5/32-inch barbed fittings, terminal connectors, and necessary hardware to adapt to existing wallboxes. By maintaining consistent 20 PSIG supply air, the T-4002-304 ensures stable environmental regulation in commercial and industrial settings where rugged, vibration-resistant instrumentation is required for long-term operational performance.
Key Benefits- Universal Compatibility: Engineered to convert various competitor two-pipe pneumatic thermostats to the high-performance Johnson Controls T4000 platform.
- Precise Modulation: Proportional output signal provides accurate control over pneumatic actuators based on specific space secondary loads.
- Field Flexibility: Includes multiple faceplates and a universal subplate to accommodate diverse mounting orientations and aesthetic requirements.
- Robust Design: Features a shock-resistant bimetal element designed to withstand the rigors of mechanical room and industrial environments.
What is the difference between Direct Acting and Reverse Acting in this kit?
The T-4002-304 is a Reverse Acting (RA) model, meaning the output pressure increases as the sensed temperature rises. This is critical for systems where the controlled device (like a NC heating valve) requires higher pressure to close.
Does this kit include everything needed for a two-pipe conversion?
Yes, the kit is fully self-contained, including the thermostat, beige cover, mounting subplate, tubing, and barbed adapters to interface with existing 5/32" or 1/4" lines.
Can the sensitivity of the T-4002 be adjusted?
Yes, the sensitivity is field-adjustable from 0.75 to 4 psig per degree Fahrenheit, allowing technicians to fine-tune the response time of the HVAC loop.
