Siemens Building Technology Pneumatic Thermostats
Siemens Building Technology is a globally recognized leader in building automation and HVAC control, and their lineup of pneumatic thermostats represents some of the most trusted hardware in commercial building climate control. Drawing on decades of engineering expertise and the legacy of the Powers Controls brand — acquired and integrated into the Siemens portfolio — these thermostats are engineered to deliver precise, dependable temperature regulation in demanding commercial, institutional, and industrial environments.
The Powerstar® Series: Versatility for Every Application
At the core of Siemens Building Technology's pneumatic thermostat offering is the Powerstar® line. Siemens offers a wide selection of Powerstar® thermostats, including single setpoint, heating/cooling, day/night/vent, free energy band, and gradual acting configurations — making it straightforward to specify the right device for virtually any pneumatic system. Whether the application calls for a direct-acting or reverse-acting thermostat, a one-pipe or two-pipe arrangement, Powerstar® has a purpose-built model to match.
Complementing the Powerstar® lineup is the Retroline™ Retrostat Kit system, which allows facility managers and HVAC technicians to convert most existing pneumatic thermostats to the Powerstar® platform without a full system overhaul. This makes Siemens an especially practical choice for retrofit projects in older commercial buildings where pneumatic infrastructure is already in place.
The 192 & 193 Series: Precision Through Proven Mechanics
The Siemens/Powers 192 and 193 Series pneumatic room thermostats are a workhorse in the commercial HVAC world. These units use sensitive bimetals to respond to temperature change, modulating control air through a flapper-nozzle mechanism to produce a proportional output signal. That signal then modulates pneumatic valves and damper actuators in direct response to load changes in the conditioned space — enabling smooth, continuous control rather than simple on/off cycling.
The 192 and 193 Series are available in one- and two-pipe, dual temperature, day/night, and auto-changeover configurations. High-volume and low-volume output variants are available to meet the functional requirements of any building automation system, and each chassis includes a wall plate for straightforward installation using a variety of rough-in kits.
Rugged Construction for Commercial Demands
Siemens pneumatic thermostats are engineered for demanding environments, offering rugged construction and proven reliability that minimizes downtime and reduces ongoing maintenance needs. Their patented control technology helps ensure consistent room temperatures — a critical performance requirement in offices, schools, hospitals, healthcare facilities, and other commercial spaces where occupant comfort and energy efficiency go hand in hand.
For facilities already running pneumatic HVAC systems, Siemens Building Technology pneumatic thermostats offer a well-supported, code-compliant path to maintaining and upgrading climate control without the cost of converting to a fully electronic system.
