Honeywell Commercial T775M2048 Electronic Remote Temperature Controller

The Honeywell Commercial T775M2048 Electronic Remote Temperature Controller is a versatile, standalone modulating controller designed for heating, cooling, boiler, and chiller applications. Its 1/4" diameter x 2" length bulb and two sensor inputs deliver precise control, while a rugged NEMA 1 enclosure protects electronics in demanding environments. The set point spans -40 to 248°F with a differential of 1 to 150°F, making it ideal for wide-ranging process and comfort cooling needs.

This remote temperature controller supports 50 Hz (-40 to 125°F) and 60 Hz (-40 to 140°F) operation, two SPDT contacts, conduit connections, and multiple approvals (UL, CUL, CE). It handles demanding loads with contact ratings up to 10 A at 24 VAC, 9.8 A at 120 VAC, 4.9 A at 240 VAC (full load), and pilot duty up to 125 VA. Long sensor runs are possible—up to 1000 ft—thanks to a robust 1097 ohm PTC sensor and two input capability. Includes the 50021579-001 sensor for immediate use.
