Resideo Braukmann t775l2007 Electronic Temperature Controller Stage Sequencer 2 Temp Inputs 4 Spdt Relays

Product Description

The Resideo Braukmann T775L2007 is a commercial-grade electronic temperature controller designed for staging applications that demand precise remote temperature sensing and reliable switched outputs. Part of the T775 series, the T775L2007 represents the next generation of electronic controls used across commercial HVAC systems, agricultural environments, and industrial process control installations. HVAC technicians and controls specialists rely on this unit when standard mechanical controllers cannot deliver the accuracy or flexibility required for multi-stage sequencing tasks.

The T775L2007 features two sensor inputs and four SPDT relay outputs, allowing it to manage multiple temperature zones or staged equipment loads from a single controller. It accepts 24 Vac or 120/240 Vac power at both 50 Hz and 60 Hz, making it adaptable to a wide range of electrical systems. The relay contacts are rated at 10.0A resistive at 24 Vac, and 1/2 hp at both 120 Vac and 240 Vac, providing solid capacity for controlling compressors, pumps, fans, and other HVAC or refrigeration loads.

Temperature sensing is handled through a 1097 ohm PTC sensor element calibrated at 77 degrees Fahrenheit, with a setpoint range spanning -40 F to 248 F. Accuracy is rated at 1 degree Fahrenheit at 77 F, and the differential temperature range runs from 1 F to 150 F. Sensors can be located up to 1,000 feet away from the controller, making remote sensing in large commercial or agricultural buildings practical and straightforward. One sensor, part number 50021579-001, is included in the package.

The controller ships in a NEMA 1 enclosure and measures 8 5/32 inches high by 4 13/32 inches wide by 2 15/16 inches deep. It supports the Electronic Series 90 analog output type and can be expanded by adding one or two T775S modules, each providing four additional relay outputs. Operating ambient temperature range runs from -40 F to 140 F at 60 Hz.

• Two sensor inputs with remote sensing capability up to 1,000 feet for flexible installation in large facilities
• Four SPDT relay outputs rated for 24 Vac, 120 Vac, and 240 Vac loads including motors and pilot duty circuits
• Expandable design supports up to two T775S add-on modules for additional relay capacity

Product Highlights

The T775L2007 delivers electronic accuracy and versatile multi-stage sequencing for commercial HVAC, refrigeration, and agricultural temperature control applications. Its wide setpoint range, remote sensor capability, and expandable relay outputs make it a go-to controller for demanding installations.
