Siemens Building Technology 356-1005 Thermostat
The Siemens Building Technology 356-1005 is a professional-grade pneumatic thermostat from the TH 356 Limitem series, specifically engineered for high-precision temperature control in air handling units and unit ventilators. As a reverse acting thermostat (RA), this unit is designed to increase output air pressure as the sensed temperature decreases, making it a critical component for low-limit freeze protection or mixed-air control. The 30-180°F temperature range provides the necessary flexibility for both discharge air monitoring and high-limit applications in commercial HVAC mechanical rooms.
Built with a rugged 18-inch rigid bulb sensing element, this Siemens TH 356 Limitem utilizes an Invar steel rod and copper motor tube to ensure fast response times and long-term calibration stability. The dual-valve design is a standout feature for contractors, as it significantly reduces "bleeding" or wasted control air, optimizing the efficiency of the entire pneumatic loop. This duct mount thermostat comes complete with a swivel flange and all necessary mounting hardware to facilitate a straightforward installation in various duct geometries where air stratification might otherwise complicate accurate readings.
Key Benefits for the Jobsite:- Efficient Air Management: The two-valve design eliminates constant air consumption, preserving compressor life and system pressure.
- Stratification Accuracy: The 18-inch sensing tube provides a broad average reading across the duct profile, preventing localized hot or cold spots from triggering false system responses.
- Robust Construction: Features a high-quality Invar steel rod for reliable thermal expansion response across the full 30-180 degree Fahrenheit spectrum.
- Versatile Application: Ideal for use as a primary controller for unit ventilators or as a high/low temperature limit in complex air handling sequences.
- How do I adjust the sensitivity on this model? Sensitivity is field-adjustable by relocating the internal sensitivity spring. Loosen the dial and adjustment screws as per the technician's manual to set the desired psi-to-degree ratio.
- Can this be used for water temperature control? Yes, when paired with a compatible immersion well, the 356-1005 can effectively monitor and control water temperatures in piping systems.
- What is the typical supply air requirement? Standard operation requires clean, dry, oil-free control air between 18 and 30 psi.
