Danfoss 017L003166 RT140L Temp Control

The Danfoss 017L003166 RT140L is a heavy-duty single-pole double-throw (SPDT) thermostat engineered for demanding industrial and marine refrigeration environments. This RT series temperature control features a specialized vapor charge and is designed for applications where the sensor temperature remains higher than the bellows temperature, effectively preventing condensation issues. With an adjustable temperature range of 0°C to 45°C (32°F to 113°F) and a high 15-25K adjustable differential, the RT140L provides precise HVACR system regulation for cooling and heating circuits. The IP66 rated enclosure ensures reliable operation in high-moisture settings, protecting the internal mechanism against dust and high-pressure water jets. Its high-load electrical contact system handles up to 10A AC-1 loads, making it a rugged solution for automated compressor control and alarm signaling. For contractors, the G 1/2 A capillary connection and 2-meter capillary length offer versatile mounting configurations in tight mechanical rooms.

• Enhanced Environmental Protection: The IP66 waterproof housing ensures long-term reliability in harsh mechanical environments and wash-down areas.
• Application Specific Charge: Specifically designed for neutral zones and applications where the sensor temperature exceeds the ambient temperature at the bellows.
• Durable Switching Mechanism: Equipped with a robust SPDT contact system that minimizes arcing and ensures consistent electrical switching under high duty cycles.
• Ease of Integration: Standard screw terminals and a universal mounting bracket design simplify field replacement for existing Danfoss RT thermostats.

What is the maximum sensor temperature for the RT140L?
The unit is designed to handle a maximum operating temperature at the sensor of up to 150°C (302°F) without damaging the internal charge or bellows assembly.

Can this control be used for both cooling and heating?
Yes, the SPDT changeover switch allows for terminal connection to either a cooling circuit (break on rise) or a heating circuit (make on rise) depending on your wiring configuration.

How do you adjust the mechanical differential?
The differential is adjusted via the internal setting disc located under the housing cover. For the 017L003166, the mechanical differential is adjustable between 1.8K and 8K to prevent short-cycling of the compressor.
