Resideo Braukmann t678a1437 Remote Bulb Commercial Temperature Controller 0 to 100 F 5 Ft Capillary

Product Description

The Resideo Braukmann T678A1437 is a remote bulb commercial temperature controller designed to regulate the temperature of air or liquids in ducts, pipes, tanks, and boilers. This thermostat is built for demanding commercial HVAC and plumbing applications where accurate and reliable temperature control is essential. The copper sensing bulb is connected via a 5-foot capillary tube, allowing the controller to be mounted away from the sensing point. This makes it well suited for installations where direct access to the medium being monitored is limited or impractical. HVAC technicians, mechanical contractors, and plumbing professionals rely on remote bulb thermostats like the T678A1437 for hydronic heating systems, commercial boiler controls, process piping, storage tanks, and ventilation ductwork. The controller operates across a temperature range of 0 to 100 degrees Fahrenheit, covering a wide span of typical commercial heating and cooling applications. It outputs control signals through 2 SPDT switch contacts, which allow it to drive relay-based systems and integrate easily into existing control panels and building automation equipment. The unit is compatible with both 120 Vac and 240 or 277 Vac power supplies and supports both 50 and 60 Hz electrical systems, giving installers flexibility across a broad range of commercial environments. The controller measures 5 and 5 eighths inches high, 2 inches wide, and 2 and 5 eighths inches deep, making it a compact and practical choice for panel or wall mounting. With a single sensor input and a copper bulb sensor element, the T678A1437 delivers straightforward, dependable temperature sensing for commercial control loops. This unit is a direct choice for trades professionals who need a proven, code-compatible thermostat for commercial heating and cooling systems.
