Siemens Building Technology 192-220 Stat
The Siemens 192-220 is a professional-grade pneumatic room thermostat designed for precision temperature regulation in commercial and institutional HVAC systems. This direct acting (DA), single-setpoint controller utilizes a highly sensitive bimetal sensing element to provide proportional control of pneumatic valves and damper actuators. Operating on a 1-pipe system architecture, this unit is engineered for low air capacity applications where a steady 18 to 25 psi supply pressure is maintained. The Celsius scale (7°C to 30°C) dial ensures accurate setpoint adjustments, while the integral, field-adjustable limit stops allow technicians to define strict temperature ranges for energy management compliance. The chassis includes a control pressure test port, enabling rapid output verification without removing the cover, which significantly streamlines routine maintenance and system balancing for field service contractors.
Key Benefits- Precise Proportional Control: Specifically calibrated for linear response to temperature changes, ensuring stable room environments.
- Streamlined Installation: The included universal wall mounting plate is compatible with a wide range of standard rough-in terminal boxes.
- Durable Maintenance Profile: Features field-replaceable components including the thermometer, setpoint dial, filters, and internal restrictor.
- Natural Energy Management: Integral limit stops prevent occupant tampering and excessive heating or cooling loads.
- Retrofit Ready: Designed to accommodate 5/32-inch OD plastic tubing for seamless integration into existing pneumatic control loops.
How do I verify the calibration during a service call?
Using a 192-633 test gauge and needle adapter, you can access the test port directly through the cover. At 22°C with the setpoint matched to ambient temperature, the control pressure should read approximately 7.5 psi.
Can this 1-pipe model be used in high-capacity applications?
The Siemens 192-220 is a low-capacity 1-pipe unit. For high-capacity requirements—such as controlling multiple large actuators—it is typically recommended to utilize a 2-pipe relay-type thermostat or an external volume booster relay.
What is the proper procedure for adjusting sensitivity?
Sensitivity is factory-set at 2.5 psi/°F but is field-adjustable from 1 to 4 psi/°F using the graduated scale on the internal bracket. Note that any adjustment to sensitivity requires a full recalibration of the calibration screw.
