Its award winning design assures contractors and home owners peace of mind and long term savings in operating costs. Lochinvar has raised the KNIGHT standard to even greater heights. The SMART SYSTEM? control with color display gives installers and maintenance personnel a greater level of control than ever before. It'

s easy to access all the information they need to setup, troubleshoot and monitor all boiler functions. Additionally, two cascading options allow the installer to fine-tune sequencing of multiple boiler installations. More than ever, KNIGHT is the best choice for traditional hydronic space heating, radiant floor heating and indirect domestic hot water applications. The Best You Can Buy Is Now Even Better! All KNIGHT Boilers meet or exceed the most stringent requirements, with less than

20 ppm NOx. The KNIGHT Boiler has been designated as one of the Most Efficient ENERGY STAR qualified products in 2014. Knight XL Commercial Need more BTU'

7 Inputs from 55,000 to 399,999 Btu/hr. See Knight Wall Mount Literature (WHN) for more details. Lead-Lag Cascade The lead boiler modulates with demand to capacity. As demand increases, additional boilers fire and modulate to capacity. This continues, with additional boilers firing and modulating to capacity until all units are operating. Every

24 hours, the SMART SYSTEM automatically shifts the lead boiler role to the next in the sequence, distributing lead-lag runtimes equally. Efficiency Optimized Cascade This feature optimizes the modulation capabilities of the Boiler Plant while evenly distributing run time across all cascaded boilers. Every

24 hours the SMART SYSTEM automatically shifts the 1st boiler on role to the next in the sequence, distributing run time equally. SMART SYSTEM Cascade option allows

2 -

8 boilers to be sequenced. Selectable Cascade Options When multiple KNIGHT boilers are installed together, the SMART SYSTEM built-in sequencer can be set for Lead-Lag cascade or Efficiency Optimized cascade operation. At-a-Glance Color-Coding The SMART SYSTEM? is the most advanced integrated boiler control on the market today. Larger LCD Screen Displays more information. Soft Keys For simple programming. Navigation Dial For fast transitions from screen to screen and easy adjustment of settings. USB Port USB port permits connection to a laptop computer.
