Siemens Building Technology 192-222 Stat
The Siemens 192-222 Powers Room Thermostat is a heavy-duty pneumatic temperature controller engineered for two-pipe proportional control in commercial HVAC systems. This Direct Acting (DA) model maintains precise setpoints within a 7 to 30°C range, utilizing a highly sensitive bimetal element to modulate branch pressure based on ambient temperature changes. Designed for seamless integration into Siemens Building Technology frameworks, the 192-222 is a terminal equipment controller typically used for heating and cooling applications via valve or damper actuator positioning. The rugged construction and field-replaceable cartridge filter ensure long-term reliability in high-traffic environments. This analog pneumatic thermostat features a dual-scale (F/C) display and requires a 22 psi (152 kPa) supply pressure for optimal operation. Contractors and facility engineers value this unit for its simplified calibration process and compatibility with standard wall plate configurations, making it a staple for maintaining pneumatic control loops in legacy and modern builds.
- Enhanced Sensitivity: The bimetal sensing element provides high-accuracy response to load variations, stabilizing terminal unit performance.
- Modular Design: Standard two-pipe configuration allows for direct acting control of pneumatic actuators without complex external relays.
- Versatile Application: Ideal for zone control in commercial settings where air-driven automation is preferred over electronic systems.
- Field Serviceability: Includes accessible test ports for branch pressure verification and easy setpoint adjustment via the integrated dial.
Common Questions
How do I calibrate the Siemens 192-222 thermostat?
Calibration involves using a test gauge to monitor branch line pressure at the mid-point of the hardware's range. Adjust the calibration screw until the branch pressure matches the required signal for the current ambient temperature.
Can this thermostat be used in a Reverse Acting (RA) application?
No, the 192-222 is specifically a Direct Acting (DA) pneumatic controller. For cooling or heating sequences requiring an increase in pressure as temperature drops, a Reverse Acting model must be sourced.
What supply air quality is required for this pneumatic unit?
To prevent orifice clogging, supply air must be clean, dry, and oil-free. It is recommended to use instrument-grade compressed air filtered to at least 5 microns.
