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
Comfort
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
• 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,

Intelli-
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 low­pressure 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 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
Johnson Controls Unitary Products 5
251934-YTG-G-0708
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.
Wide Range of Indoor Airflows - All supply air blowers
are equipped with a belt drive that can be adjusted to meet the exact requirements of the job. A high static drive option is available for applications with a higher CFM and/ or static pressure requirement.
Warranty - All models include a 1-year limited warranty
on the complete unit. Compressors and electric heater elements each carry a 5-year warranty. Aluminized steel and stainless steel tubular heat exchangers carry a 10­year warranty.
Factory Installed Options
YORK® offers several equipment options factory installed, for the ZJ/ZR/ZF Series.
Single Input Electronic Enthalpy Economizers -
Includes a slide-in / plug-in damper assembly with fully modulating spring-return motor actuator capable of introducing up to 100% outdoor air with nominal 1% leakage type dampers.
The enthalpy system contains one sensor that monitors the outdoor air and determines when the air is cool enough and dry enough to provide free cooling.
The rainhood is painted to match the basic unit and must be field-assembled before installing.
• BAS-Ready Economizer - Includes a slide-in / plug-in
damper assembly with fully modulating spring-return motor actuator with zero to 95-degree rotation capable of introducing up to 100% outdoor air with nominal 1% leakage type dampers.
Actuator requires 2-10 VDC input from an external source, such as a field-installed or factory-installed BAS controller. BAS-ready actuators have an adjustable auxiliary end-switch for optional power exhaust control.
For units with optional VAV or Simplicity® Intelli­Comfort™ control, a factory-installed, dry bulb sensor determines if outdoor air temperature is low enough to provide free-cooling operation. (Field-installed humidity sensors for either outdoor air or outdoor & return air
streams are available for single enthalpy and differential enthalpy configurations, respectively).
The rainhood is painted to match the basic unit and must be field-assembled before installing.
Power Exhaust - Our economizer options are available
with power exhaust. Whenever the outdoor air intake dampers are opened for free cooling, the exhaust fan will be energized to prevent the conditioned space from being over-pressurized during economizer operation.
The exhaust fan, motor and controls are installed and wired at the factory. The rain hood must be assembled and installed in the field.
The power exhaust option can only be used on bottom duct configurations.
Motorized Outdoor Air Intake Damper - Includes a
slide-in / plug-in damper assembly with a 2- position, spring return motor actuator which opens to a pre-set position whenever the supply air blower is operating and will drive fully closed when the blower unit shuts down.
The rain hood is painted to match the basic unit and must be field assembled before installing.
Barometric Relief Damper - This damper option can be
used to relieve internal building air pressure on units with an economizer without power exhaust. This accessory includes a rain hood, a bird screen and a fully assembled damper. With bottom duct connections, the damper should be mounted over the opening in the return air panel. With horizontal ductwork, the accessory should be mounted on the return air duct.
Phenolic Coated Evaporator And Condenser Coils -
Special coating process that utilizes Technicoat 10-1" processes. Coating is applied by total immersion of the complete coil for maximum protection.
Electric Heaters - wired for single point power supply.
These nickel chromium heater elements are provided with limit and automatic reset capability to prevent operation at excessive temperatures.
Variable Air Volume (VAV) - A factory-installed variable
frequency drive (VFD), mounted in the Blower Access compartment, is used to control the speed of the indoor blower motor in order to maintain a constant static pressure in the supply duct. A pressure transducer and VAV control board are mounted inside the control box. The drive comes completely wired and pre-programmed from the factory.
An optional, factory-installed manual bypass switch available with factory-installed VFD can be found in the Blower Motor Access compartment. The switch can be used to either route power to the VFD for modulating control of the blower motor, to bypass the drive and operate the motor at full speed, or to power the drive (and not the motor) for diagnostic purposes.
Due to space limitations, VAV is not available with any of the factory-installed BAS options described below, but is available with ‘BAS-ready’ models. Terminal blocks are provided in the control box for field wiring of the customer­installed BAS.
6 Johnson Controls Unitary Products
A ‘VFD-ready’ option provides the provisions for a customer-installed drive. The unit comes with a mounting bracket installed in the Blower Access compartment which may accommodate other vendor’s drives depending on their size. In order to utilize the unit’s mounting bracket, the maximum recommended drive dimensions are as follows:
For 5-hp motor applications........................ 13” H x 6” W x 7” D
For 7.5 thru 15-hp motor applications ........ 13” H x 8” W x 8” D
If the drive will not fit in the allotted space, then it will have to be mounted elsewhere; either within the building on a perpendicular wall which is not subjected to excessive temperature, vibration, humidity, dust, corrosive gas, explosive gas, etc., or within an appropriate enclosure rated for outside installation to safeguard against moisture, dust and excessive heat.
A terminal block located in the control box is provided for field connection of the VFD controls.
Hot Gas Bypass - To allow for low cooling load operation,
a direct-acting pressure-modulating bypass control valve installed on the system #1 discharge line is used to divert high temperature, high pressure refrigerant around the TXV in order to maintain a desired minimum evaporator pressure. HGBP is standard on all units with VAV and optional with CV units.
Filter Options - Standard units are shipped with 2" throw-
away filters installed. 2" pleated and 4" pleated filters are offered as a factory installed option.
Convenience Outlet - This 110 volt outlet can be
"powered" by the unit with a stepdown transformer or you may order the unit with a "non-powered" convenience outlet that can be wired in the field.
Disconnect Switch - For gas heat units and cooling units
with electric heat, a HACR breaker sized to the unit is provided. For cooling only units, a switch sized to the largest electric heat available for the particular unit is provided. Factory installed option only.
Double Wall Construction - Optional double wall
construction is available to provide smooth inner surfaces for easy and effective cleaning to reduce risk of dirt and bacterial accumulation. Fiberglass insulation is sandwiched between heavy gauge steel sheets to form a durable, rigid casing to withstand higher working pressures and impact forces.

Reheat Mode Sequence Of Operation
The reheat control board allows the user to select two different modes of operation via a jumper connection on the board. (See Reheat Control Board.) Each mode is described below. Refer to Reheat Controls - Part 1 and Part 2 when reading this section.
“Normal” Mode
When the reheat control board (RCB) detects a need for dehumidification (24VAC) at "HUM" via the field supplied dehumidistat connected to RHTB-1 and RHTB-2 and there is not a call for cooling, it energizes the hot gas relay (HGR), which energizes the 3-way valve (SOL 3), the condenser coil valve (SOL 2), and de-energizes the reheat coil bleed valve (SOL 1). The Y1 signal is passed to the unit control board (UCB), which engages circuit # 1, resulting in circuit #1 reheat mode operation.
When the room thermostat calls for first stage cooling, with or without a call for dehumidification, the RCB senses a signal through "Y1", de-energizing the HGR, which de-energizes SOL 3 and SOL 2, and energizes SOL 1, engaging circuit # 1, resulting in circuit #1 cooling mode operation.
Indoor blower operation is initiated upon a call for first stage cooling, second stage cooling or dehumidification.
Anytime there is a call for 2 stages of cooling, the unit will not operate in the reheat mode, even if there is a call for dehumidification at "HUM".
The unit will not operate in the reheat mode if there is any call for heating.
On units with economizers, the unit will not operate in the reheat mode if there is a call for cooling and the economizer is operating as first stage of cooling.
All safety devices function as previously described.
"Alternate” Mode
When the RCB detects a need for dehumidification (24VAC) at "HUM" via the field supplied dehumidistat connected to RHTB-1 and RHTB-2, and there is not a call for cooling, it energizes the HGR, which energizes the SOL 3, SOL 2, and de-energizes SOL 1. The unit then operates with circuit #1 in reheat mode and circuit #2 in cooling mode.
When the room thermostat calls for first stage cooling while there is still a call for dehumidification, no operational change is made. The call for cooling is ignored and the unit continues to operate with circuit #1 in reheat mode and circuit #2 in cooling mode.
When the room thermostat calls for second stage cooling, the RCB senses a signal through "Y1" & "Y2" and de-energizes the HGR, which de-energizes SOL 3 and SOL 2, and energizes SOL 1. Both circuits operate in the cooling mode.
Indoor blower operation is initiated upon a call for first stage cooling, second stage cooling or dehumidification.
Anytime there is a call for 2 stages of cooling, the unit will not operate in the reheat mode, even if there is still a call for dehumidification at "HUM".
When the room thermostat calls for second stage cooling, the RCB senses a signal through "Y1" & "Y2" and engages circuit #1 and circuit #2 in the cooling mode.
