Features and Benefits

Standard Features

High Efficiency - High efficiency units reach as high as 12.4 EER. Gas/electric units have electronic spark ignition and power vented combustion with steady state efficiencies of 80%. These efficiencies exceed all legislated minimum levels and provide low operating costs.

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™, 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 intake damper assembly should be mounted 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 low- pressure switches. Internal compressor protection is standard on all compressors. Crankcase heaters are standard on reciprocating compressors. Scroll compressors do not require crankcase heaters. Phase Monitors are standard on units with scroll compressors. This accessory monitors the incoming power to the unit and protects the unit from phase loss and reversed phase rotation.

Advanced Controls - Simplicity™ ZJ/ZR/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 0°F 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.

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 times, you’re out” philosophy. The high and low- pressure 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

R-410A specifications

York R-410A is a widely recognized and highly efficient refrigerant used in modern air conditioning systems. Developed as an environmentally friendly alternative to R-22, R-410A has gained popularity in the HVAC industry due to its numerous advantageous features and characteristics.

One of the main features of York R-410A is its ability to provide superior cooling performance. This refrigerant operates efficiently at both high and low temperatures, allowing systems using it to maintain optimal indoor climates even during extreme weather conditions. Its high energy efficiency ratio (EER) and seasonal energy efficiency ratio (SEER) ratings make it a preferred choice for energy-conscious consumers, resulting in lower energy bills and a reduced carbon footprint.

Technologically, York R-410A systems feature advanced compressor designs that enhance their overall reliability and performance. These compressors are often equipped with variable-speed technology, enabling them to adjust their output to match the cooling demands of the space. This not only improves comfort levels but also leads to efficient energy consumption, reducing wear and tear on the equipment over time.

Another significant characteristic of York R-410A is its non-ozone-depleting properties. Unlike its predecessor R-22, which is being phased out due to its damaging effects on the ozone layer, R-410A is designed to minimize environmental impact. Its lower global warming potential (GWP) further underscores its role in promoting sustainability within the HVAC sector.

Furthermore, York R-410A systems are engineered with enhanced safety features. The refrigerant is non-toxic and non-flammable, which makes it safer for use in both residential and commercial applications. Additionally, its high thermal stability reduces the risk of breakdown or leakage, contributing to longer system lifespans and lower maintenance costs.

In conclusion, York R-410A stands out as a cutting-edge refrigerant that combines efficiency, safety, and environmental responsibility. With its advanced technologies and remarkable characteristics, it meets the demands of modern air conditioning requirements while paving the way for a sustainable future in HVAC systems. Adopting York R-410A not only benefits individual users through improved comfort and lower energy bills but also plays a vital role in protecting our planet's ozone layer and mitigating climate change.
