Siemens Building Technology 192-840 Retrostat Kit
The Siemens Building Technology 192-840 Retrostat Kit provides a professional-grade solution for upgrading legacy pneumatic room thermostats to the high-performance Powerstar TH192 standard. This direct-acting, two-pipe, single-setpoint kit is engineered to replace existing units from manufacturers like Johnson Controls, Honeywell, Barber-Colman, and Robertshaw. The unit features a highly sensitive bi-metal thermostatic element and a flapper nozzle for precise proportional control of pneumatic valves and damper actuators. Each Siemens TH192 conversion kit is factory-calibrated at 72°F with a 7.5 psi output, specifically designed for a Fahrenheit scale range of 45 to 85°F. The package includes a TH192 pneumatic thermostat, a desert beige cover with a field-replaceable thermometer, a "goof plate" for large wall openings, and all necessary mounting hardware. Integrated features such as field-adjustable limit stops and a dedicated test port allow for rapid pressure checks and system trimming without cover removal, ensuring efficient installation and long-term HVAC pneumatic controls maintenance.
Key Benefits- Universal Compatibility: Seamlessly replaces obsolete pneumatic stats including JCI T-4002, Honeywell TP970, and Robertshaw T18 series.
- Enhanced Accuracy: Factory-calibrated for immediate service with a sensitivity range of 1 to 4 psi/°F.
- Installation Efficiency: Multi-slotted "goof plate" conceals oversized wall scars, eliminating the need for extensive drywall repair.
- Field Serviceability: Features an accessible test port and replaceable filters, restrictors, and thermometers to maximize uptime.
- Versatile Configuration: Cover can be field-adjusted to either conceal or expose the setpoint indicators based on facility requirements.
Which pneumatic thermostats can the 192-840 replace?
This kit is designed to retrofit most 2-pipe single-setpoint models, specifically cross-referencing with the Honeywell TP970 series, Johnson Controls T-4002, and Barber-Colman TK-1001 devices.
Does this kit include everything needed for a conversion?
Yes, it includes the TH192 chassis, a desert beige cover, adapter frame (goof plate), setpoint dial, and the necessary wrench for calibration and cover security.
What is the control action of this specific model?
The 192-840 is a direct-acting (DA) device, meaning the output pressure increases as the sensed temperature rises.
