At its core is a 10K Type III NTC thermistor, which provides accurate analog temperature readings to a connected controller or BAS panel. The unit features an integrated LCD display and a precision rotary encoder with a knob and incremental feedback, allowing occupants or technicians to interact with setpoints directly at the sensor. The white plastic enclosure with white label is suited for clean, finished interior wall installations. HVAC controls technicians and building automation professionals are the primary installers of this device.\u003c\/p\u003e\u003cp\u003eThe pl-t500-wwl is intended for indoor room-level temperature sensing in commercial and residential HVAC systems that use compatible PROLON controllers. It mounts on a standard wall surface to capture zone temperature and provide a local user interface for setpoint adjustment. The rotary encoder with incremental feedback makes it practical for occupant-accessible zones where manual setpoint changes are permitted by the control sequence. The LCD display gives clear, real-time feedback of current conditions without requiring a separate handheld tool or laptop at the sensor location.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e10K Type III NTC thermistor for accurate, reliable temperature sensing\u003c\/li\u003e\n\u003cli\u003eIntegrated LCD display for real-time temperature and setpoint readout\u003c\/li\u003e\n\u003cli\u003ePrecision rotary encoder knob with incremental feedback for local setpoint adjustment\u003c\/li\u003e\n\u003cli\u003eWhite plastic enclosure with white label for clean finished-space aesthetics\u003c\/li\u003e\n\u003cli\u003eWall-mounted form factor suited for occupied zone installations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style room temperature sensor for use with PROLON building automation and HVAC control systems that support 10K Type III NTC thermistor inputs.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by a licensed HVAC controls technician or building automation specialist. Power down the controller and de-energize the low-voltage wiring circuit before making sensor connections. Mount the enclosure on a flat interior wall surface away from direct sunlight, drafts, supply air diffusers, and heat sources that could skew temperature readings. Follow the PROLON controller wiring documentation and applicable low-voltage wiring codes when terminating sensor leads.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSensor Type\u003c\/strong\u003e: 10K Type III NTC Thermistor\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDisplay\u003c\/strong\u003e: Integrated LCD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUser Interface\u003c\/strong\u003e: Rotary encoder knob with incremental feedback\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnclosure Material\u003c\/strong\u003e: Plastic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnclosure Color\u003c\/strong\u003e: White\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLabel Color\u003c\/strong\u003e: White\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: PROLON\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: pl-t500-wwl\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PROLON","offers":[{"title":"Default Title","offer_id":51267953492274,"sku":"PL-T500-WWL","price":298.37,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/308913094.jpg?v=1780695446","url":"https:\/\/voomisupply.com\/products\/prolon-pl-t500-wwl-digital-room-temperature-sensor","provider":"Voomi Supply","version":"1.0","type":"link"}
