Triangle Tube Prestige Solo 399 Details
The Triangle Tube Prestige Solo 399 is a highly efficient condensing boiler, designed for advanced hydronic heating systems. Its superior performance is largely attributed to the proprietary CTRLMax (formerly ACVMax) Boiler Management System, which intelligently monitors and controls heat delivery for optimal efficiency. This system provides a user-friendly graphical interface, simplifying navigation and access to critical operational data.
Beyond its core specifications, the Prestige Solo 399 boasts a versatile EZ Setup feature, enabling quick customization of heating and domestic hot water (DHW) settings. Installers can easily configure parameters like outdoor reset curves, fixed setpoints, and Warm Weather Shutdown temperatures, adapting the boiler to various application requirements without extensive manual adjustments.
For enhanced flexibility, the boiler offers multiple control inputs, including two central heating (CH) call inputs, each capable of having its own outdoor reset curve. This allows for sophisticated zone management in multi-temperature systems, maximizing comfort and energy savings by matching boiler output precisely to demand.
Safety is paramount with integrated features like a factory-installed pressure sensor type Low Water Cut Off (LWCO), which monitors system pressure and provides additional low water protection by sensing water temperatures. The boiler also includes a robust Freeze Protection feature that activates at 46°F (8°C) to prevent boiler damage, although it's crucial to note it protects the boiler itself, not the entire heating system.
The Prestige Solo 399 is engineered for modern installations, supporting direct venting and sealed combustion. It allows for cascade functionality, enabling up to six units to operate cohesively as a single, powerful heating system without external controllers. Additionally, it integrates with building management systems (BMS) via a Modbus interface for comprehensive control and monitoring.
Its heat exchanger is designed to operate effectively in a condensing mode, making it highly suitable for radiant heating applications, even those utilizing non-oxygen barrier tubing. The unit automatically derates its input by approximately 2% for every 1,000 feet of altitude, ensuring consistent performance without requiring manual adjustments to the burner system.
Maintenance is made simpler through clearly defined schedules for both homeowners and qualified service technicians. This includes daily, monthly, and bi-annual checks for owners, and comprehensive annual servicing by professionals to ensure long-term reliability and efficiency. Critical components like the condensate drain assembly, which must remain filled with water, are highlighted for attention.
