Siemens Building Technology 193-215 Thermostat

The Siemens 193-215 is a professional-grade two-pipe pneumatic thermostat designed for heavy-duty commercial HVAC applications requiring precise Heating/Cooling (H/C) control. This Powerstar Free Energy Band model utilizes a sensitive bimetal element to provide proportional, direct-acting (DA/DA) control of valves and damper actuators. It is engineered to maximize energy efficiency by establishing a deadband—an adjustable range where neither heating nor cooling occurs—minimizing mechanical wear and energy waste. As the designated replacement for the Powers 2212-318 and the Johnson Controls T-4054-1, it offers a seamless retrofit for legacy building automation systems.

Built for durability in the field, this thermostat supports a dual setpoint configuration and features a high air capacity for managing multiple terminal devices. The unit operates within a standard range of 45°F to 85°F and includes a control pressure test port, allowing technicians to verify output without removing the desert beige cover. Whether you are maintaining a school, hospital, or high-rise office, the 193-215 ensures consistent occupancy comfort through reliable pneumatic room temperature control.

• Direct Replacement: Fully compatible with legacy 2212-318 and T-4054-1 models, reducing downtime during retrofits.
• Energy Deadband: The Free Energy Band technology prevents overlapping of heating and cooling cycles.
• Field Adjustable: Features integral limit stops and sensitivity adjustment (1 to 4 psi/°F) for precise system tuning.
• High Air Capacity: Integrated relay allows for the control of multiple actuators or valves without additional boosters.
• Modular Serviceability: Includes field-replaceable filters, restrictors, and thermometers to extend the service life of the chassis.

• How do I calibrate the Siemens 193-215? Use a 192-632 calibration tool to adjust the setpoint dials while monitoring the supply air, typically between 18 and 25 psi.
• Is this compatible with single-pipe systems? No, this is a two-pipe high-capacity chassis; however, it can be adapted for three-pipe high-volume applications if necessary.
• Does it include the cover? This part number typically refers to the thermostat chassis and wall plate; verify if your application requires a separate exposed or concealed adjustment cover.
