Features and Benefits

Standard Features

• 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

• 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.

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.

• 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.

• Advanced Controls - Simplicity™ ZJ/ZR/ZF control

boards have standardized a number of features

previously available only as options or by utilizing

additional controls.

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.

• 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

• 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.

temperature is low or when free cooling is available.

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.

The Simplicity® control board used in this product

will effectively operate the cooling system down to

0°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

• 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.

accessories may be needed for stable operation at

temperatures below 30°F.

• 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.

• Factory Mounted Outdoor Air Dampers - All models are

available with these "factory mounted" outdoor air damper

options:

• 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.

• Single enthalpy economizer with or without power

exhaust

• BAS-ready economizer with or without power exhaust

• Motorized outdoor air damper

• 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.

• 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,

• Safety Monitoring - The control board monitors the

high and low-pressure switches, the freezestats, the gas

alarm on ignition failures, compressor lockouts and

repeated limit switch trips.

• 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.

• 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.

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.

• 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.

For units with optional VAV or Simplicity® Intelli-

Comfort™ 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).

• 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.

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.

• 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.

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.

• 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.

• 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.

• 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.

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.

• 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 10-

year warranty.

forces. The heavy-duty construction provides excellent

acoustic and thermal insulation and eliminates erosion of

insulation material and contamination of the air stream.

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.

• York Commercial Comfort System (YCCS) - Provides

rooftop system integration for YCCS single zone, change-

over bypass and VAV systems.

• Smoke Detectors - (supply air & return air) The smoke

detectors stop operation of the unit by interrupting power

to the control board if smoke is detected within the air

compartment.

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 customer-

installed BAS.

Factory installed smoke detectors in the return air, may

be subjected to freezing temperatures during “off” times

due to out side air infiltration. these smoke detectors have

an operational limit of 32°F to 131°F. smoke detectors

installed in areas that could be out side those limitations

will have to be moved to prevent having false alarms.

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,

and circuit #2 in cooling mode.

• Supply Air Smoke Detector

• Return Air Smoke Detector

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.

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.

“Normal” 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.

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.

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 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

The unit will not operate in the reheat mode if there is any call

for heating.

All safety devices function as previously described.
