Honeywell T775B2016 Temperature Controller

The Honeywell T775B2016 is a robust, stand-alone electronic remote temperature controller designed for precision in demanding HVACR applications. Engineered with a NEMA 4X enclosure, this unit is built to withstand moisture and corrosion, making it ideal for agricultural, industrial, and commercial settings. It features dual SPDT relay outputs and a dedicated floating output, providing versatile control for valves and dampers. With a setpoint temperature range of -40°F to 248°F and an accuracy of +/- 1 degree at 77°F, it ensures stable thermal management. The 1097 Ohms PTC sensor allows for lead lengths up to 1000 feet, offering flexibility in remote sensing layouts. This model serves as the Honeywell T775 electronic stand-alone controller solution and is the designated A19ANC-2 direct replacement, ensuring a seamless retrofit for legacy Johnson Controls installations. Whether managing multi-stage heating or cooling, the wide throttling range and adjustable differential provide the granular control contractors require for system optimization.

• Flexible Power Options: Supports 24 Vac or 120/240 Vac field wiring for broad application compatibility.
• High Contact Rating: Features a 9.8 Amp full load rating at 120 Vac, capable of handling demanding inductive loads.
• Extended Sensor Distance: Maintain calibration integrity with sensor runs up to 1000 feet from the controller.

Common Questions

How do I configure the floating output on the T775B2016?
The floating output is designed for 3-wire modulating actuators. You must configure the setup menu to define the drive-open and drive-closed run times to match your specific valve or damper motor specifications.

Is this unit compatible with NTC thermistors?
No, this controller is calibrated specifically for 1097 Ohms PTC (Positive Temperature Coefficient) sensors. Using standard 10k or 20k NTC thermistors will result in inaccurate readings and system errors.

Can I use this for outdoor ambient sensing?
Yes, provided the sensor is rated for outdoor use. The NEMA 4X housing of the controller itself is suitable for mounting in wash-down or outdoor environments when installed with appropriate conduit seals.
