Siemens Building Technology 192-850 Stat
The Siemens Building Technology 192-850 is a high-performance pneumatic thermostat designed for precision temperature control in commercial HVAC systems. This direct acting (DA) unit is part of the Powerstar Retroline series, specifically engineered to replace aging pneumatic controls from major manufacturers including Johnson Controls, Honeywell, and Barber Colman. Featuring a Celsius scale setpoint, the 192-850 utilizes a highly sensitive bimetal element and a flapper nozzle assembly to provide a proportional output signal to terminal equipment. Its 2-pipe configuration supports high air capacity, and the kit includes a versatile wall mounting plate and "goof plate" to facilitate seamless retrofitting into the original footprint. This single setpoint (SSP) controller operates within a standard range of 7 to 30°C and is factory-calibrated at 7.5 psi (52 kPa) to ensure immediate out-of-the-box accuracy when integrated into an 18 to 25 psi main air supply line.
- Universal Compatibility: Serves as a primary retrofit kit for legacy pneumatic systems, replacing common models like the Johnson Controls T-4002 or Honeywell TP970.
- Field Adjustability: Features an adjustable sensitivity (1 to 4 psi/°F) and integral limit stops to fine-tune local environment response.
- Technical Reliability: The rugged bimetal sensing element provides a consistent 0.1°F (0.06°C) temperature response for reliable comfort control.
- Maintenance Friendly: Includes an accessible control pressure test port allow technicians to monitor output without removing the desert beige Cycolac cover.
What is the primary application for the Siemens 192-850?
This pneumatic room thermostat is used to modulate pneumatic valves and damper actuators in institutional or commercial heating and cooling systems where a direct-acting, single-temperature Celsius control is required.
How do I calibrate this unit in the field?
Calibration is typically set for 22°C at 7.5 psi. Technicians can use the integrated test port and a standard calibration wrench to adjust the setpoint dial and sensitivity graduations to match the specific local system requirements.
Is the cover included in this Retroline kit?
Yes, the 192-850 kit includes a desert beige plastic cover that can be configured for either exposed or concealed setpoint adjustment and thermometer viewing.
