gas valve, if applicable, and the temperature limit

switch on gas heat units. The unit control board will

alarm on ignition failures, compressor lockouts and

repeated limit switch trips.

FEATURES

All models are available with a wide variety of factory-

mounted options such as stainless steel heat exchangers,

electric heaters, phase monitor, convenience outlet, dirty filter

switch, disconnect switch, smoke detectors, and coil guard to

make them suitable for almost every application.

•

Nuisance Trip Protection- To prevent nuisance

trouble calls, the control board uses a “three strikes,

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 compressor.

All units are self-contained and assembled on full perimeter

base rails with forklift holes on three sides and holes for over-

head rigging. Every unit is completely piped, wired, charged

and tested at the factory to simplify the field installation and to

provide years of dependable operation.

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.

All models (including those with an economizer) are suitable

for either bottom or horizontal duct connections. For bottom

duct, remove the sheet metal panels from the supply and

return air openings through the base of the unit. For horizon-

tal duct, remove the supply and return air panels on the rear

of the unit.

All models are available with these “factory mounted” outdoor

air damper options:

All units have long lasting powder paint cabinets with 1000

hour salt spray test approval under ASTM-B117 procedures.

•

Single enthalpy economizer

Motorized outdoor air damper

All models are CSA listed.

•

Warranty - All models include a one-year limited parts

warranty on the complete unit. Compressors and electric

heater elements carry a five-year warranty. Gas heat

exchangers carry a 10-year parts warranty.

Supply air blowers are equipped with either a direct drive or a

belt drive that can be adjusted to meet the exact require-

ments of the job.

•

Gas Heat Operation - All single phase models with gas

heat have minimum annual fuel utilization efficiency

(AFUE) of 80%. All three phase models with gas heat

have minimum steady state efficiency of 80%. Each sec-

tion 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.

All compressors are equipped with internal pressure relief.

Every refrigerant circuit includes a liquid line filter-drier, a high

pressure switch and a suction line with a freezestat and low

pressure/loss of charge switch to protect all system compo-

nents.

•

S implicity Controls - S implicity 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 0ºF outdoor ambient without additional assis-

tance. Optionally, the control board can be pro-

grammed to lockout the compressors when the

outdoor air temperature is low or when free cooling

is available.

•

Electric Heat Operation - All electric heat models 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 uni-

form distribution of air across the heating elements.

Every element is fully protected against excessive tem-

perature by thermal limit switches.

•

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.

The power supply wiring can be routed into the control

box through a threaded pipe connection (field supplied)

in the base pan of the unit or through a knockout in the

wiring panel on the side of the unit.

•

Fan Delays - Fan on and fan off delays are fully pro-

grammable and are independent of one another. All

units are programmed with default values based

upon their configuration of cooling and heat.

•

BAS Controls - York’s Sunline™ series units offer factory

mounted BAS controls such as S implicity INTELLI-Com-

fort™, Novar, Honeywell, Johnson, and CPC.

Safety Monitoring - The control board monitors the

high and low-pressure switches, the freezestats, the

scheduling is built-in. Two different modes of demand

ventilation are achieved through the INTELLI-Comfort™

using CO2 sensors. It uses an inside CO2 sensor to per-

form Demand Ventilation. It can also use an Outside

CO2 sensor to perform Differential Demand Ventilation.

It uses a Patented Comfort Ventilation algorithm to pro-

vide comfortable ventilation air temperature. The pat-

ented economizer-loading algorithm will protect the

equipment when harsh operating conditions exist.

Humidity in the occupied space or return duct can be

monitored and controlled via humidity sensors and the

on-board connection for hot gas re-heat system. It uses

the INTELLI-Start™ algorithm to maximize energy sav-

ings by recovering the building from the Unoccupied Set-

points to the Occupied Setpoints just in time for the

power to the control board if smoke is detected within the

air compartment.

Factory installed Smoke Detectors in the return air,

may be subjected to freezing temperatures during

“off” times due to outside air infiltration. These

1. These ratings include the compressor and the condenser fan motors but not the supply air blower motor. The total condenser fan

motor power input is 0.36kW. Refer to the SUPPLY AIR BLOWER PERFORMANCE Table for the kW of the supply air blower motor.

2. These capacities are gross ratings. For net capacity, determine the kW of the supply air blower motor from the SUPPLY AIR BLOWER

PERFORMANCE Table, multiply this value by 3.425 MBH/kW to determine the motor heat, and deduct this heat from the gross capacity

of the unit.

1. Deduct these resistance values from the available external static pressure shown in SUPPLY AIR BLOWER PERFORMANCE Tables.

2. Add these resistance values to the available static resistance values on SUPPLY AIR BLOWER PERFORMANCE Tables.

3. The pressure through the economizer is greater for 100% outdoor air than for 100% return air. If the resistance of the return air

duct system is less than 0.25 IWG, the unit will deliver less CFM during full economizer operation.
