  1. Front End Loading &Multi Temperature Loop Control

  2. Benefits • Affordable • Eases System Complexity • Accessory to the Knight Boiler • No need to learn additional logic • Single Source Responsibility • Flexible • 3 Independent Outdoor Reset Curves • Satisfy Up to 3 Different Demands

  4. How it works… 110° 140° 180°

  5. Who is the Direct Competition? • Tekmar-360 • Triangle Tube-SMV

  6. Tekmar 360 • Single Reset Temperature • Single Pump Control • Boiler Enable Logic • A Second Display, Terminology and Logic to Learn for the Contractor and the Users

  7. Tekmar 360 Display

  8. Triangle Tube SMV • Single Reset Temperature • Single Pump Operation • No Communication with Boiler • Night Setback Schedule • A Second Display, Terminology and Logic to Learn for the Contractor and the User

  9. Loop Control Advantages • Maximizes Boiler Efficiency • 3 Individual Reset Curves(Pumps and MV) • Works in Concert with Onscreen Boiler Display • Programming • System Feedback and communication • Single Source for Support

  10. Questions?

  11. Front End Loading

  12. Capabilities/Combinations • Crest with Copper-Fin II • Crest with Power-Fin • Knight with Copper-Fin II • Armor with Copper-Fin II • Different Sized Knights/Armors

  13. Additional Equipment Required • 1 Exception: • Crest PC Software is necessary when the combination of Crest and Power-Fin is used NONE

  14. Benefits of Front End Loading • Decreased Up Front Equipment Cost • Increased System Turndown • Increased System Efficiency

  15. Up front Cost • (3) FBN2000 = $148,332 • (2) FBN2000 & (1) CHN2072 = $121,719 (-$26,613) • (1) FBN2000 & (2) CHN2072 = $95,106 (-$53,226)

  16. Increased System Turndown • (3) CHN2072 = ≈10:1 Turndown Ratio • $68,493 List Price • (2) CHN2072 & (1) FBN2000 = 77:1 Turndown • $95,106 List Price =Decreased Energy and Maintenance Costs

  17. Piping/Design Considerations • Primary/Secondary • Low Temperature Protection

  18. Front End Loading Sequence of Operation • Cascade will default to lead lag • Smallest Highest Efficiency Product Will Fire First • If multiple same size products, the first on will rotate • Smallest low efficiency products will be called on first then larger inputs will be called on as demand is increased.
