The 6.5 – 12.5 ton Predator™ series and 15 – 23 ton Large Sunline™ series ultra-high efficiency products achieve improved efficiency with intelligent control and operational flexibility. MILWAUKEE – (January 22,2019) – The YORK® brand of Johnson Controls has released two new options to deliver maximum energy efficiency and comfort control to commercial spaces. Predator and Large Sunline roof top units achieve maximum energy efficiencies to lower operating costs

Original Press Release: YORK Redefines Efficient Comfort Control with the Introduction of Two New Ultra-High Efficiency Commercial Rooftop Units

The embedded Smart Equipment™ controls display alarm messages and identify faults. They are offered with optional MaganDry™ reheat system and variable air volume. The intelligent discrete fan control offers fan speed variation depending on the cooling stages engaged.

The units are equipped with two independent refrigerant circuits and two UltraTech™ compressors.

To customize your graph, drag the points to where you want them (they only go up or down, not left or right). It basically just asks you what fan speed you want at what temperature. The Graph curve is simple but has enough customization potential to work for just about anyone. The Graph curve is probably the best of the three. The Target curve will only change the fan speed if the temperature reaches either the minimum or the maximum. The difference between Target and Linear is what happens between the minimum and maximum temperatures.

For example, in my curves, the fans will always spin at 100% speed if the temperature is 95 C. When the minimum or maximum temperature is reached for both of these cards, their corresponding speed will trigger. Next, you need to set a minimum speed and a maximum speed.
