COMPRESSOR

Copeland Scroll Ultra Tech™ Two-Stage Compressor

Compressor features high

efciency with uniform

suction ow, constant

discharge ow and high

volumetric efciency and

quiet operation.

Compressor consists of

two involute spiral scrolls

matched together to generate

a series of crescent shaped

gas pockets between them.

During compression, one

scroll remains stationary

while the other scroll orbits

around it.

Gas is drawn into the outer

pocket, the pocket is sealed

as the scroll rotates.

As the spiral movement continues, gas pockets are

pushed to the center of the scrolls. Volume between the

pockets is simultaneously reduced.

When pocket reaches the center, gas is now at high

pressure and is forced out of a port located in the

center of the xed scrolls. During compression, several

pockets are compressed simultaneously resulting in a

smooth continuous compression cycle.

Continuous ank contact, maintained by centrifugal

force, minimizes gas leakage and maximizes efciency.

Scroll compressor is tolerant to the effects of slugging

and contaminants. If this occurs, scrolls separate,

allowing liquid or contaminants to to be worked toward

the center and discharged.

On the xed scroll there are two bypass ports in the rst

suction pocket. On the

outside of the xed scroll

there is a “slider ring” that

is controlled by an internal

solenoid that will rotate and

cover the bypass ports.

When the thermostat calls

for rst-stage cooling, the

bypass ports are open and

the compressor operates

at 67% capacity, creating

more cost-effective and efcient compressor operation.

The bypassed refrigerant is returned to the compressor

housing through the bypass ports. When the thermostat

calls for second-stage cooling, the internal solenoid is

energized, the slider ring rotates and covers the bypass

ports, and the compressor operates at full capacity.

Low gas pulses during compression reduces

operational sound levels.

Compressor motor is internally protected from

excessive current and temperature.

FEATURES

XC21 - 2 to 5 Ton Air Conditioner / Page 4

COMPRESSOR (CONTINUED)

Compressor is installed in the unit on specially

formulated, resilient rubber mounts for better sound

dampening and vibration free operation.

Crankcase Heater

Crankcase heater prevents migration of liquid

refrigerant into compressor and ensures proper

compressor lubrication.

CONTROLS

icomfort™ Control

Advanced control communicates

information about various

operating parameters in

the air conditioner to the

optional icomfort Touch™

Communicating Thermostat to

constantly maintain the highest

level of comfort, performance and

efciency available.

Connections for connecting a

conventional heating/cooling

thermostat are also provided on

the control.

Auto Conguration - On start-up the control

automatically sends a description of the unit to

the optional icomfort Touch™ Communicating

Thermostat to automatically congure the number of

stages and features available.

Control also features:

• Compressor anti-short cycle delay. User selectable

with communicating thermostat - 1, 2, 3, 4 or 5

minutes. Default setting is 5 minutes.

Compressor must operate in rst stage a minimum

of 5 seconds before second stage operation is

permitted.

• Low voltage protection prevents 2nd stage

compressor operation when voltage is not within the

specied range.

• High and low pressure switch monitoring with

provisions for lockout.

• Five-Strike lockout protection protects compressor.

• Discharge line temperature and sensor monitoring.

• Lennox Humiditrol® Whole Home Dehumidication

System (EDA) compatible.

• EEPROM storage of all local congurations.

Lennox Systems Operations Monitor

(icomfort™ Control Feature)

Onboard Lennox® Systems Operations Monitor (LSOM)

provides detailed information for proper preventative

maintenance and fast, easy servicing.

Displays the most common fault conditions (electrical

and mechanical) through the icomfort Touch™

Communicating Thermostat or through the ALERT

and TRIP lights on the control. ALERT LED (yellow) -

communicates an abnormal system condition through a

unique ash code. The ALERT LED will ash a number

of times consecutively, pause and then repeat the

process. The number of consecutive ashes, dened

as the Flash Code, correlates to a particular abnormal

condition. The codes can indicate one of the following:

long run time, system pressure trip (discharge or suction

pressure out-of-limits or compressor overloaded), short

cycling, locked rotor, open circuit, open start circuit

(current present only in run circuit), open run circuit

(current present only in start circuit), welded contactor

(compressor runs continuously), or low voltage (control

circuit < 17VAC). TRIP LED (red) - indicates there is a

demand signal from the thermostat but no current to the

compressor is detected by the monitor.

OPTIONS

Compressor Low Ambient Cut-Off

Non-adjustable switch (low ambient cut-out) prevents

compressor operation when outdoor temperature is

below 35°F.

Compressor Hard Start Kit

Single-phase units are equipped with a PSC

compressor motor.

This type of motor normally does not need a potential

relay and start capacitor.

In conditions such as low voltage, kit may be required to

increase the compressor starting torque.

Indoor Blower Off Delay Relay

Delays the indoor blower-off time during the cooling

cycle. Required if outdoor unit is used with a

conventional heating-cooling thermostat and air handler

(not icomfort™ control). See furnace or air handler

specications to determine if relay is needed.

Indoor Blower Speed Relay Kit

Relay kit provides optimum humidity control conditions

by automatically reducing indoor blower speed during

continuous fan or rst-stage compressor operation.

Low Ambient Kit

Air conditioner will operate satisfactorily down to 45°F

outdoor air temperature without any additional controls.

Kit can be added in the eld enabling unit to operate

properly down to 30°F.

A Freezestat should be installed on compressors

equipped with a low ambient kit.

A Compressor Low Ambient Cut-Off should be added to

terminate compressor operation below recommended

operation conditions.
