Important InformationThe Honeywell T775B2032 is an operating temperature controller, not an independent safety-limit controller.
Applications requiring high-temperature safety shutdown, low-temperature protection, or other safety functions must use separately approved safety devices as required.
Please confirm the complete model number, power requirements, wiring configuration, relay specifications, and temperature sensor compatibility before installation.
Professional installation by a qualified HVAC or electrical technician is recommended.
