Honeywell 14004406-300 Cover

Professional field technicians understand that a durable housing is non-negotiable for maintaining the calibration and integrity of pneumatic control systems. The Honeywell 14004406-300 (also identified as 14004406-300/U) is a heavy-duty vertical humidistat cover engineered specifically for TP970 and TP9600 series pneumatic thermostats and humidistats. Finished in a professional satin chrome, this no-display cover provides a clean, tamper-resistant solution for commercial and industrial environments where setpoint visibility or manual adjustment is restricted to authorized personnel. This replacement humidistat cover ensures a precise fit, eliminating the risk of bypass air or environmental contaminants interfering with sensitive bimetal sensing elements. Whether you are performing a routine HVAC pneumatic system maintenance or replacing a damaged 14004406-300 unit, this assembly integrates seamlessly with existing mounting backplates. Its robust construction protects against physical impact and dust, ensuring that your Honeywell pneumatic controls function at peak efficiency without constant recalibration requirements.

• Universal Compatibility: Specifically designed to fit Honeywell TP970 and TP9600 series pneumatic controllers, ensuring a secure, flush-mount installation.
• Tamper-Resistant Design: The no-display window and lack of external adjustment knobs prevent unauthorized setpoint changes in high-traffic areas.
• Industrial Durability: The satin chrome finish provides superior resistance to corrosion and wear, maintaining a professional appearance in mechanical rooms.
• Streamlined Installation: Designed for vertical mounting, the assembly slides onto standard backplates and secures via standard set screws for rapid field replacement.

• Is the 14004406-300 compatible with horizontal mounting? No, this specific model is engineered for vertical orientation. For horizontal applications, a different cover configuration is required to align with the backplate mounting ears.
• What is the difference between the 14004406-300 and the 14004406-300/U? These parts are functionally and physically identical; the "/U" suffix simply designates a universally packaged commercial version.
• Does this cover include a thermometer window? This is a "no display" or blank cover model, perfect for security-conscious installations where user-facing readouts are not desired.
