Siemens Building Technology 356-0750 Thermostat
The Siemens 356-0750 Limitem is a heavy-duty, pneumatically-operated direct acting thermostat engineered for precise temperature control in demanding commercial HVAC environments. Featuring a rugged 18-inch rigid bulb sensing element, this TH 356 Limitem model is the industry standard for monitoring air temperatures in air handling units, unit ventilators, and discharge air ducts where thermal stratification is a concern. The construction utilizes a durable copper motor tube paired with an invar steel rod, ensuring stability and accuracy across its 30°F to 180°F range. Its two-valve design is specifically calibrated to minimize air waste, maintaining system efficiency without compromising 3 to 15 psi control signal integrity. Whether used as a primary controller or a low limit control, the 356-0750 provides the reliable mechanical feedback necessary for pneumatic building automation systems. Duct mounting hardware, including a flange and lock nut, is included for immediate field installation.
Key Benefits:
- Broad Temperature Range: Reliable 30°F to 180°F setpoint range covers most mixed air and discharge air applications.
- Stratification Resistance: The 18-inch rigid copper bulb provides a larger sensing surface area to prevent false readings in large ducts.
- Pneumatic Efficiency: Precision two-valve internal design eliminates unnecessary air bleed, reducing compressor load.
- Rugged Construction: Invar steel rod and copper tube sensing element offer high resistance to ambient temperature shifts at the controller body.
- Universal Mounting: Includes all necessary hardware for secure duct mounting and the 1/8-inch NPT connections standard for pneumatic lines.
Common Questions:
How do I calibrate the Siemens 356-0750 in the field?
Field calibration is achieved by adjusting the dial screw while monitoring the branch pressure at the test port. Ensure the branch pressure reads 7 to 8 psi when the sensed temperature matches the dial setting to ensure accurate pneumatic thermostat response.
Can this thermostat be used for water temperature control?
Yes, while primarily used for duct air, the 356-0750 can be installed in a well for liquid immersion applications, making it a versatile rigid bulb thermostat for hydronic systems.
What is the difference between direct acting (DA) and reverse acting (RA)?
This 356-0750 is a direct acting model, meaning its output signal pressure increases as the sensed temperature increases. This is essential for controlling cooling valves or dampers that require increased pressure to open.
