Danfoss 017-509966 RT14 Controller

The Danfoss 017-509966 RT14 is a heavy-duty temperature controller designed for reliability in demanding industrial and marine HVACR applications. Built with a robust SPDT contact function, this RT14 thermostat operates within a precise temperature range of 23°F to 86°F (-5°C to 30°C), making it an ideal choice for neutral zone control or standard temperature switching where economic or safety consequences are critical. The unit features a remote bulb sensor with a 2000mm (approximately 78 3/4 inch) capillary tube, allowing for flexible mounting and accurate sensing away from the controller body. With its IP66 enclosure rating, the 017-509966 provides superior protection against dust and high-pressure water jets. Technicians can fine-tune system performance using the adjustable differential, which ranges from 2°C to 8°C at the minimum setting and up to 10°C at the maximum. This Danfoss RT series controller utilizes an adsorption charge and supports an automatic reset, ensuring consistent operation without manual intervention after a trip event.

Key Benefits:

• Rugged Environmental Protection: The IP66 rated housing ensures long-term durability in harsh mechanical rooms or marine environments.
• Versatile Contact Rating: Features a high-capacity SPDT switch rated for AC1=10A and AC15=3A at 400V, compatible with a wide range of motors and solenoids.
• Precise Control: The adjustable differential allows contractors to prevent short-cycling and optimize equipment longevity.
• Remote Sensing Capability: A 2-meter capillary tube provides the reach needed for complex evaporator or liquid sensing configurations.
• Technical Compliance: Meets strict industrial standards including CE, GL, and EAC approvals for global machinery integration.

Common Questions:

• What is the maximum sensor temperature for the RT14? The remote bulb is designed to withstand a maximum sensor temperature of up to 302°F (150°C) without damage to the charge.
• Can this controller be used for cooling and heating applications? Yes, the SPDT contact function allows the 017-509966 to be wired to either break or make a circuit on temperature rise, facilitating both types of control.
• What is the electrical connection type? The unit uses a screwed cable entry (2xPg 13.5) for secure field wiring, accommodating solid or stranded wires up to 2.5 mm2.
