Part of the Honeywell Tradeline series, this thermostat translates space temperature into a modulating pneumatic output, allowing downstream pneumatic actuators and valves to maintain setpoint conditions. The unit ships with a satin chrome cover that suits commercial interior aesthetics while protecting the sensing and adjustment components. Licensed HVAC technicians working on commercial pneumatic systems are the primary installers of this device.\u003c\/p\u003e\n\u003cp\u003eThe TP973B2171 is suited for commercial and light-industrial HVAC applications where pneumatic control infrastructure is already in place. Typical installations include office buildings, schools, hospitals, and other facilities operating pneumatic zone control systems. It is designed as a wall-mounted room thermostat, replacing aging pneumatic controls in existing pneumatic distribution networks.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePneumatic output signal modulates to control heating, cooling, or combined systems\u003c\/li\u003e\n  \u003cli\u003eTradeline series replacement part for straightforward sourcing and installation\u003c\/li\u003e\n  \u003cli\u003eSatin chrome cover included for a finished appearance in commercial interiors\u003c\/li\u003e\n  \u003cli\u003eWall-mounted design for standard room thermostat positioning\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement for commercial pneumatic thermostat applications in facilities with existing pneumatic HVAC control systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed HVAC technician familiar with pneumatic control systems. Shut off the main air supply to the pneumatic control circuit before disconnecting or connecting any tubing. Follow all applicable local mechanical codes and manufacturer guidelines when routing and connecting pneumatic tubing. Verify system air supply pressure is within the operating range specified for the control system before returning the circuit to service.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eControl Type\u003c\/strong\u003e: Pneumatic\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCover Finish\u003c\/strong\u003e: Satin Chrome\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Tradeline\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: Honeywell\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: TP973B2171\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HONEYWELL","offers":[{"title":"Default Title","offer_id":67591159578930,"sku":"TP973B2171","price":389.08,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/169757820.jpg?v=1790420757","url":"https:\/\/voomisupply.com\/products\/honeywell-tp973b2171-pneumatic-thermostat","provider":"Voomi Supply","version":"1.0","type":"link"}
