Danfoss 017-501466 Control

The Danfoss 017-501466 is a professional-grade RT3 thermostats designed for heavy-duty industrial refrigeration and ventilation applications. This SPDT temperature control operates within a precise range of -58°F to 158°F, making it a versatile choice for walk-in coolers, freezers, and harsh ambient environments. Utilizing a remote bulb sensor with a 2-meter capillary tube, it allows for accurate sensing away from the main switch body, providing installation flexibility in tight mechanical spaces. The Danfoss RT series is known for its high degree of enclosure protection (IP66) and adjustable differential, which allows technicians to fine-tune the cut-in and cut-out points to prevent short-cycling. Engineered with silver-plated contacts, the Danfoss 017-501466 ensures reliable electrical switching for fans, compressors, or alarms. For contractors, the RT3 stands out for its mechanical durability and consistent calibration across the entire temperature gradient.

Common Installation and Operation Questions

How do I adjust the differential on the Danfoss RT3?
The differential is adjusted using the internal setting disc. Technicians should refer to the scale on the front of the unit and the nomograms provided in the technical manual to determine the exact cut-in and cut-out values based on the setpoint.

Can this control be mounted in any orientation?
Yes, the RT3 series is designed for versatile mounting, but it is recommended to install it with the cable entries pointing downward to prevent moisture ingress into the housing.

What electrical load can the SPDT switch handle?
The contact system is designed for high-capacity switching, typically handling up to 10A AC-1 (inductive) and 4A AC-3 (motor) loads, making it compatible with most solenoid valves and small motor starters.
