  • Page 5: Introduction

    Better Economy... Lower total cost of ownership • Johnson Controls provides a standard product offering that meets the latest ASHRAE 90.1 energy efficiency requirements. • Fully modulating gas heat and greater steps of capacity control offer superior off- design performance while maintaining optimum occupant comfort.

  • Page 6: Features And Benefits

    80–250 kW depending on the single package unit model size. The number of stages varies by size and voltage, but all have a minimum of two stages of capacity. Units with electric heat are ETL listed. JOHNSON CONTROLS...
  • Page 7 0.0°F through the use of suction and discharge pressure transducers on the circuit(s). Pressure Transducers with Readout Capability – This option includes suction and dis- charge pressure transducers on each circuit and provides pressure readout of all circuits at the unit control panel. JOHNSON CONTROLS...
  • Page 8 Barometric Relief – This option does not include an exhaust or return fan, but rather uses barometric relief dampers to exhaust air from the building. The dampers will open relative to the building pressure. The opening pressure is adjustable via a spring tension adjustment. JOHNSON CONTROLS...
  • Page 9 The supply fan can be optionally equipped with a piezo ring to precisely measure the amount of air delivered to the conditioned space. The speed of the supply fan is controlled by a VFD. JOHNSON CONTROLS...

  • Page 13: Application Data

    Unit clearances are designed so that technicians have enough space between units, building walls, and edges of building to gain access safely. In cases where space is limited, please call your local Johnson Controls representative for addi- tional information.
  • Page 14 Erecting a fence around the unit is common practice. • Roof curb – Johnson Controls offers optional roof curbs designed specifically for the Series 100 footprint. These curbs come in full perimeter or open condenser models and are shipped disassembled and require field assembly and installation.
  • Page 15 HVAC equipment. If the application calls for horizontal supply and return air, Johnson Controls can ship it from the factory as a horizontal unit. This option eliminates the need for field modification of equipment saving time and money.
  • Page 16 FIGURE 2 - TRADITIONAL OVERHEAD VAV AIR DELIVERY SYSTEM For VAV applications, the Johnson Controls Series 100 unit uses a VFD to modulate fan speed and maintain a constant duct static pressure. VFDs offer superior control over the operation of the unit at part load, and offer the additional benefits of quieter and more ef- ficient operation when compared to IGV.
  • Page 17 Johnson Controls offers a powered return fan that is located in the return plenum. This fan operates coincidentally with the supply fan and draws return air back through the return ductwork and into a pressurized plenum.
  • Page 18 Control is accomplished via either a discharge damper or a VFD. Johnson Controls recommends the use of a VFD to reduce energy consumption, sound levels and improved reliability due to fewer moving parts.
