    • 1. Compressor Lockout (CLO): To prevent mechanical (compressorized) operation of the unit during cold outdoor conditions where there is a risk of returning liquid refrigerant back to the compressors.
    • 2. Low Limit Control (LLC): To prevent the supply air from dropping below a specified setpoint by utilizing the units first stage heating means when there is a demand for cooling during cold outside conditions.

    • DESCRIPTION
    • UNIT CABINET
    • INDOOR (EVAPORATOR) FAN ASSEMBLY
    • OUTDOOR (CONDENSER) FAN ASSEMBLY
    • REFRIGERANT COMPONENTS
      • a. Shall be scroll type, direct drive, internally protected with internal high-pressure relief and over temperature protection. The hermetic motor shall be suction gas cooled and have a voltage range of + or – 10% of the unit nameplate voltage.
      • b. Shall have internal spring isolation and sound muffling to minimize vibration and noise, and be externally isolated on a dedicated, independent mounting.
      • a. Evaporator and condenser coils shall have aluminum plate fins mechanically bonded to seamless internally enhanced copper tubes with all joints brazed. Special Phenolic coating shall be available as a factory option.
      • b. Evaporator and condenser coils shall be of the direct expansion, draw-thru design.
      • a. Independent fixed-orifice or thermally operated expansion devices.
      • b. Solid core filter drier/strainer to eliminate any moisture or foreign matter.
      • c. Accessible service gage connections on both suction and discharge lines to charge, evacuate, and measure refrigerant pressure during any necessary servicing or troubleshooting, without losing charge.
      • d. The unit shall have two independent refrigerant circuits, equally split in 50% capacity increments.
      • a. Unit shall be complete with self-contained low-voltage control circuit protected by a resetable circuit breaker on the 24-volt transformer side.
      • b. Unit shall incorporate a lockout circuit which provides reset capability at the space thermostat or base unit, should any of the following standard safety devices trip and shut off compressor: (1) loss-of-charge/Low-pressure switch, (2) high-press...
      • c. If any of the above safety devices trip, a LED (light-emitting diode) indicator shall flash a diagnostic code that indicates which safety switch has tripped.
      • d. Unit shall incorporate “AUTO RESET” compressor over temperature, over current protection.
      • e. Unit shall operate with conventional thermostat designs and have a low voltage terminal strip for easy hook-up.
      • f. Unit control board shall have on-board diagnostics and fault code display.
      • g. Standard controls shall include anti-short cycle and low voltage protection, and permit cooling operation down to 0 °F.
      • h. Control board shall monitor each refrigerant safety switch independently.
      • i. Control board shall retain last 5 fault codes in non volatile memory, which will not be lost in the event of a power loss.
    • GAS HEATING SECTION (If Equipped)
      • a. Primary and auxiliary high-temperature limit switches.
      • b. Induced draft pressure sensor.
      • c. Flame roll out switch (manual reset).
      • d. Flame proving controls. Unit shall have two independent stages of capacity (60% 1st stage, 100% 2nd stage).
