Honeywell Commercial T775A2009 Electronic Remote Temperature Controller

The Honeywell Commercial T775A2009 Electronic Remote Temperature Controller is a reliable, standalone solution for precise temperature control in commercial HVAC and process systems. This Electronic Remote Temperature Controller uses a 1/4 inch diameter by 2 inch length bulb and is designed for indoor use with a NEMA 1 enclosure and conduit connections, ensuring durable performance in demanding environments.

Operating ranges cover -40 to 125°F at 50 Hz and -40 to 140°F at 60 Hz, with a Set Point range of -40 to 248°F and a Differential of 1 to 150°F. The unit features a single SPDT contact with robust ratings suitable for varying voltages, including 10 A at 24 VAC (resistive) and up to 9.8 A at 120 VAC or 4.9 A at 240 VAC (full load). It also supports higher locked rotor and pilot duty specifications. A single sensor input uses a 1097 Ohm PTC element at 77°F, with a maximum sensor distance of 1000 feet. The package includes sensor 50021579-001 and is UL (US/Canada), CUL, CE, and C‑Tick approved, making it compatible with a wide range of commercial systems. Applications span heating, cooling, boiler, and chiller control.
