• Complete Extended-Reach Mounting Kit: Includes concrete pad, wall brackets, and vibration isolation components
• Full Long-Distance Communication System: Integrated smart control components with extended-range capability

The 50-foot line sets represent a significant 43% increase in maximum installation distance compared to standard 35-foot kits, enabling installation in challenging architectural scenarios like multi-floor applications, detached structures, or complex routing requirements.

This system delivers professional-grade performance metrics even with maximum-length line set installations:

• Distance-Optimized Efficiency: Maintains 22 SEER2 and 8.2 HSPF-5 ratings even with extended line set lengths
• Cold-Climate Performance Preservation: Provides reliable heating in temperatures as low as -13°F regardless of installation distance
• Variable-Speed Compensation Technology: Automatically adjusts operation to overcome the minor effects of extended refrigerant paths
• Intelligent Flow Management: Advanced algorithms ensure proper refrigerant distribution across both zones even at maximum distances
• Wide Operating Range: Delivers rated capacity across an extended temperature spectrum regardless of line set length

These distance-optimized performance capabilities allow the system to serve as a primary heating and cooling solution even in challenging installations where standard-length systems would be inadequate, without sacrificing the energy efficiency that translates to significant operational cost savings.

This advanced system incorporates comprehensive control technologies that function flawlessly regardless of installation distance:

• Long-Range SmartHVAC Mobile Application: Provides complete system control from anywhere via Wi-Fi connectivity
• Extended Communication Protocols: Maintains reliable connection between all system components regardless of distance
• Independent Zone Scheduling: Allows separate programming for each zone to optimize comfort and efficiency
• Signal Integrity Protection: Enhanced communication design prevents data degradation over longer connection distances
• Energy Consumption Monitoring: Real-time and historical usage data helps optimize efficiency even with extended installations
• Distance-Compensating Algorithms: Adjusts system operation to maintain optimal performance regardless of line set length

The intelligent control system ensures responsive, reliable operation regardless of the distance between components, maintaining the same intuitive user experience as standard-length installations.
