Honeywell Commercial T775R2043 Electronic Remote Temperature Controller

Honeywell Commercial T775R2043 Electronic Remote Temperature Controller is a versatile, standalone control designed for precise temperature management in heating, cooling, boiler, and chiller systems. It features a 1/4 inch diameter by 2 inch length bulb, dual sensor inputs, and a wide setpoint range from -40 to 248°F, making it ideal for demanding commercial environments.

For durable installation, the unit uses a NEMA 1 enclosure with conduit connection and carries trusted UL, CUL, CE, and C-Tick approvals. It operates across 50 Hz and 60 Hz service, with a temperature sensing range of -40 to 125°F at 50 Hz and -40 to 140°F at 60 Hz, plus a differential of 1 to 150°F.

With a relay output that can reset, the controller handles multiple load conditions: 10 A at 24 VAC (resistive); 9.8 A at 120 VAC; 4.9 A at 240 VAC (full load); pilot duty up to 125 VA at 120/240 VAC. It supports maximum sensor distance up to 1000 ft and includes two 50021579-001 sensors. The sensor element is a 1097 Ohm PTC at 77°F, ensuring reliable response for heating, cooling, boiler, and chiller applications.
