Description
The Honeywell T675A1102 is a heavy-duty remote bulb temperature controller engineered to regulate the temperature of air or liquids in a wide range of HVAC and hydronic applications, including ducts, pipes, tanks, and boilers. Built for reliability in demanding commercial and industrial environments, this controller offers a broad operating range and flexible voltage compatibility to suit virtually any installation.
Key Features
- Regulates temperature of air or liquids in ducts, pipes, tanks, and boilers
- Wide setpoint temperature range: 160°F to 260°F
- Maximum operating temperature: 280°F
- Adjustable differential temperature range: 3°F to 10°F
- Dual voltage compatibility: 120Vac or 240/277Vac
- Remote bulb sensing for accurate, remote temperature measurement
Application
The T675A1102 is ideal for high-temperature control scenarios where precise regulation is critical. Its remote bulb design allows the sensing element to be placed directly in the medium being controlled — whether that’s airflow in a duct, fluid in a pipe, or liquid in a tank or boiler — while the controller body is mounted in a convenient, accessible location. The wide differential adjustment (3–10°F) allows technicians to fine-tune the control response to match system requirements and minimize short-cycling.
