H COMPRESSOR Copeland Scroll Ultra Tech Two-Stage Compressor Compressor features high efficiency with uniform suction flow, constant discharge flow and high volumetric efficiency 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 fixed scrolls. During compression, several pockets are compressed simultaneously resulting in a smooth continuous compression cycle. Continuous flank contact, maintained by centrifugal force, minimizes gas leakage and maximizes efficiency. 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 fixed scroll there are two bypass ports in the first suction pocket. On the outside of the fixed 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 first-stage cooling, the bypass ports are open and the compressor operates at 67% capacity, creating more cost-effective and efficient 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. XC21-2 to 5 Ton Air Conditioner / Page 3
I FEATURES 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 efficiency available. Connections for connecting a conventional heating/cooling thermostat are also provided on the control. Auto Configuration - On start-up the control automatically sends a description of the unit to the optional icomfort Touch Communicating Thermostat to automatically configure 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 first 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 specified 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 Dehumidification System (EDA) compatible. EEPROM storage of all local configurations. 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 flash code. The ALERT LED will flash a number of times consecutively, pause and then repeat the process. The number of consecutive flashes, defined 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 specifications 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 first-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 field 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. XC21-2 to 5 Ton Air Conditioner / Page 4
