Gas/electric units have electronic spark ignition and power vented combustion with steady state efficiencies of 80%. • Balanced Heating • Gas Heat - All gas heat units are built with two heating sections for two equal stages of capacity control. Each section includes a durable heat exchanger with aluminized steel or optional stainless steel tubes, a redundant gas valve, spark ignition, power venting, an ignition module for 100% shut-off and all of the safety controls required to meet the latest ANSI standards. The gas supply piping can be routed into the heating compartment through a hole in the base pan of the unit or through a knockout in the piping panel on the front of the unit. • Electric Heat - All electric heat models (factory installed only) are wired for a single power source and include a bank of nickel chromium elements mounted at the discharge of the supply air blower to provide a high velocity and uniform distribution of air across the heating elements. Every element is fully protected against excessive current and temperature by fuses and two thermal limit switches. The power supply wiring can be routed into the control box through a threaded pipe connection in the base pan of the unit or through a knockout in the wiring panel on the front of the unit. • BAS Controls - York’s Sunline™ series units offer factory mounted BAS controls such as Simplicity ® Intelli-Comfort II ™, Novar, Honeywell, Johnson, York Commercial Comfort System (YCCS) and CPC. • Convertible Airflow Design - All models (including those with an economizer) are suitable for either bottom or horizontal duct connections. Models with factory installed power exhaust are suitable for bottom duct connections only. For bottom duct, you remove the sheet metal panels from the supply and return air openings through the base of the unit. For horizontal duct, you replace the supply and return air panels on the rear of the unit with a side duct flange accessory. • Factory Mounted Outdoor Air Dampers - All models are available with these "factory mounted" outdoor air damper options: • Single enthalpy economizer with or without power exhaust • BAS-ready economizer with or without power exhaust • Motorized outdoor air damper • Barometric Relief Damper A fixed outdoor air intake assembly will be shipped in the return air compartment of all units ordered without an economizer or motorized outdoor air damper option. The assembly includes a rain hood with a damper that can be set for 10, 15 or 25% outdoor air. With bottom duct connections, the fixed outdoor air intake assembly should be mounted Johnson Controls Unitary Products over the opening in the return air panel. With horizontal ductwork, it should be mounted on the return air duct. • System Protection - Suction line freezestats are supplied on all units to protect against loss of charge and coil frosting when the economizer operates at low outdoor air temperatures while the compressors are running. Every unit has solid-core liquid line filter-driers and high and lowpressure switches. Internal compressor protection is standard on all compressors. Phase Monitors are optional on all units. This accessory monitors the incoming power to the unit and protects the unit from phase loss and reversed phase rotation. • Advanced Controls - Simplicity™ ZF control boards have standardized a number of features previously available only as options or by utilizing additional controls. • Low Ambient - An integrated low-ambient control allows all units to operate in the cooling mode down to 0F outdoor ambient without additional assistance. Optionally, the control board can be programmed to lockout the compressors when the outdoor air temperature is low or when free cooling is available. The Simplicity® control board used in this product will effectively operate the cooling system down to 25°F when this product is applied in a comfort cooling application for people. An economizer is typically included in this type of application. When applying this product for process cooling applications (computer rooms, switchgear, etc.), please reference applications bulletin AE-011-07 or call the applications department for Unitary Products @ 1877-UPG-SERV for guidance. • Anti-Short Cycle Protection - To aid compressor life, an anti-short cycle delay is incorporated into the standard controls. Compressor reliability is further ensured by programmable minimum run times. For testing, the anti-short cycle delay can be temporarily overridden with the push of a button. • Lead-Lag - An integrated Lead-Lag option allows equal run time hours on all compressors, thereby extending the life of all compressors. This option is selectable on the unit control board. • Fan Delays - Fan on and fan off delays are fully programmable. Furthermore, the heating and cooling fan delay times are independent of one another. All units are programmed with default values based upon their configuration of cooling and heat. • Safety Monitoring - The control board monitors the high and low-pressure switches, the freezestats, the gas valve, if applicable, and the temperature limit switch on gas and electric heat units. The unit control board will alarm on ignition failures, compressor lockouts and repeated limit switch trips. • Nuisance Trip Protection and Strikes - To prevent nuisance trouble calls, the control board uses a “three 5 1056292-XTG-A-0613 • • • • • times, you’re out” philosophy. The high and lowpressure switches and the freezestats must trip three times within two hours before the unit control board will lock out the associated compressor. • On Board Diagnostics - Each alarm will energize a trouble light on the thermostat, if so equipped, and flash an alarm code on the control board LED. Each high and low-pressure switch alarm as well as each freezestat alarm has its own flash code. The control board saves the five most recent alarms in memory, and these alarms can be reviewed at any time. Alarms and programmed values are retained through the loss of power. Reliable - From the beginning - All units undergo computer automated testing before they leave the factory. Units are tested for refrigerant charge and pressure, unit amperage, and 100% functionality. For the long term - All units are painted with a long lasting, powder paint that stands up over the life of the unit. The paint used has been proven by a 1000 hour salt spray test. Full Perimeter Base Rails - The permanently attached base rails provide a solid foundation for the entire unit and protect the unit during shipment. The rails offer rigging holes so that an overhead crane can be used to place the units on a roof. Easy Installation - Gas and electric utility knockouts are supplied in the unit underside as well as the side of the unit. Utility connections can be made quickly and with a minimum amount of field labor. All units are shipped with 2" throw-away filters installed.

Add these values to the available static resistance in the respective Blower Performance Tables. 2. Deduct these values from the available external static pressure shown in the respective Blower Performance Tables. 3. The pressure drop through the economizer is greater for 100% outdoor air than for 100% return air. If the resistance of the return air duct is less than 0.25 IWG, the unit will deliver less CFM during full economizer operation. Johnson Controls Unitary Products 25 1056292-XTG-A-0613 Drive Selection 1. Determine side or bottom supply duct application. 2. Determine desired airflow 3. Calculate or measure the amount of external static pressure. 4. Using the operating point determined from steps 1, 2 & 3, locate this point on the appropriate supply air blower performance table. (Linear interpolation may be necessary.) 5. Noting the RPM and BHP from step 4, locate the appropriate motor and/or drive on the RPM selection table. 6. Review the BHP compared to the motor options available. Select the appropriate motor and/or drive. 7. Review the RPM range for the motor options available. Select the appropriate drive if multiple drives are available for the chosen motor. 8. Determine turns open to obtain the desired operation point. Example 1. 6800 CFM 2. 2.0 iwg 3. Using the supply air blower performance table below, the following data point was located: 1020 RPM & 5.92 BHP. 4. Using the RPM selection table below, Size X and Model Y is found. 5. 5.92 BHP exceeds the maximum continuous BHP rating of the 5.0 HP motor. The 7.5 HP motor is required. 6. 1020 RPM is within the range of the 7.5 HP drives. 7. Using the 7.5 HP motor and drive, 3.5 turns open will achieve 1020 RPM.
