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.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eRemote copper bulb sensor with 5-foot capillary tube for flexible mounting and accurate temperature sensing\u003c\/li\u003e\n\u003cli\u003eCompatible with 120 Vac and 240 or 277 Vac systems at 50 or 60 Hz for wide commercial application use\u003c\/li\u003e\n\u003cli\u003e2 SPDT relay output contacts for straightforward integration into commercial control panels and HVAC systems\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eProduct Highlights\u003c\/h4\u003e\u003cp\u003eThe Resideo Braukmann T678A1437 remote bulb temperature controller offers reliable, relay-based temperature regulation for commercial ducts, pipes, tanks, and boilers across a 0 to 100 degree Fahrenheit range.
