ELI8XPV - 2 to 5 Ton Air Conditioner / Page 4 FEATURES PRECISE COMFORT® TECHNOLOGY The Variable Capacity Rotary Compressor and DC Inverter Control is an integrated system that operates together to reduce overall energy usage when compared to conventional heat pumps. 0 Variable Capacity Compressor • Rotary compressor - 024 and 036 models • Scroll compressor - 048 and 060 models • High volumetric efficiency • Uniform suction flow • Constant discharge flow • Quiet operation • Low gas pulses during compression reduces operational sound levels • Compressor motor is internally protected from excessive current and temperature • Compressor is installed in the unit on resilient rubber mounts for vibration free operation Rotary Compressor Operation (024 and 036 Models) • Rotary compressor has a cylindrical chamber • A roller is mounted to the motor shaft and is offset to rotate in the center of the chamber • Two spring -loaded vanes sweep the sides of the chamber as the roller rotates • Roller touches the chamber at a point between the intake and the discharge ports as the roller rotates • While rotating, the roller draws vapor into the chamber through the intake port • Vapor is trapped in the space between the chamber wall, the vane, and the point of contact between the roller and the chamber • As the next vane passes the contact point vapor is compressed • The space becomes smaller compressing the vapor as the roller rotates • Vapor is discharged through the discharge port Scroll Compressor Operation (048 and 060 Models) • Two involute spiral scrolls matched together 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 the 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 • Compressor is tolerant to the effects of slugging and contaminants Compressor Crankcase Heater • Protects against refrigerant migration that can occur during low ambient operation • Factory Installed Compressor Sound Dampening System • Polyethylene compressor • 2 inch thick batt fiberglass insulation • All open edges sealed with one -inch wide hook and loop fastening tape CONTROLS ODC Inverter Control • Converts AC line voltage into filtered variable DC voltage • Provides continuous compressor operation, while adjusting the capacity according to indoor temperature • Adjusts compressor output in increments as small as 1 % • The accurate sensing of the cooling or heating load prevents frequent changes in capacity and ensures efficient, economical operation • Power Factor Correction (PFC) circuit monitors the DC bus for high, low and abnormal voltage conditions to protect the compressor • Two LEDS (red and green) indicate inverter operating status and aid in troubleshooting • Noise filter reduces unwanted electromagnetic interference (EMI) • Integrated on the iComfort Communicating Control for 024 and 036 models, • Separate external inverter control for 048 and 060 models • The inverter reactor (mounted separately) adds inductance to the line between the inverter and the compressor to limit current rise and protect the compressor Optional Accessories Compressor Low Ambient Cut -Off Switch • Non-adjustable switch (low ambient cut-out) prevents compressor operation when outdoor temperature is below 35°F ELI8XPV - 2 to 5 Ton Air Conditioner / Page 5 FEATURES CONTROLS (continued) iComfort® Communicating Control • Advanced control communicates information about various operating parameters in the heat pump to the iComfort° Communicating Thermostats 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 iComfort° Communicating Thermostat to automatically configure the features available • Control also features: • Seven -Segment Display - Shows information about outdoor unit type and capacity and also displays alerts for common fault conditions (electrical and mechanical) • Low Voltage Protection - Prevents 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 • Liquid line temperature and sensor monitoring • EEPROM storage of all local configurations • Non-volatile memory storage of 100 alarm codes with display of last 10 codes for troubleshooting • Built-in low -ambient control NOTE - Two RAST connectors for a conventional heating/cooling thermostat are also provided for connecting to the control. A two -stage or single - stage thermostat can be used. Low Ambient Operation • Cooling Mode - The heat pump can operate down to 0°F outdoor air temperature in the cooling mode NOTE - A freezestat is recommended for extra protection during low ambient cooling operation. Heating Mode (Low Temperature Protection) • Outdoor unit will not operate in the heating mode when the outdoor temperature is at or below —4°F • If the unit is operating and the outdoor temperature drops below —4°F, the unit will continue to operate until the room thermostat is satisfied or the outdoor temperature drops to —15°F iComfort Thermostat Operation: Climate IQTM Technology • Optimizes dehumidification settings for specific climates to improve home comfort during cooling or heating operation iComfort Communicating Thermostat Settings: Cooling Mode • Three climate settings are available: • Dry - The system supplies higher indoor airflow at all compressor capacities, increasing efficiency by operating at a higher sensible to total ratio • Moderate - The system supplies indoor airflow that balances efficiency and comfort • Humid - The system supplies lower indoor airflow at all compressor capacities, improving humidity removal by operating at a lower sensible to total ratio Heating Mode • Two climate settings are available: • Comfort - The system reduces indoor airflow, increasing supply air temperature • Normal - Standard system operation iComfort° S30 Thermostat Setting: • Climate IQ (Auto) - Dry, Normal, Basic and Humid modes are automatically set based on the difference between the measured relative humidity and the relative humidity setting • All modes are selected on the iComfort° Communicating Thermostat Outdoor Air Temperature Sensor • Used with iComfort° Communicating Thermostats • Sensor allows thermostat to display outdoor temperature • Sensor is auto -detected when connected to thermostat ELI8XPV -

AHRI STANDARD 210/240 Cooling or heating capacities are net values, including the effects of blower motor heat, and do not include supplementary heat. Power input is the total power input to the compressor(s) and fan(s), plus any controls and other items required as part of the system for normal operation. Units which do not have an indoor air -circulating blower furnished as part of the model, i.e., split system with indoor coil only, is established by subtracting from the total cooling capacity 1250 Btu/h per 1,000 cfm, and by adding the same amount to the heating capacity. Total power input for both heating and cooling is increased by 365 W per 1,000 cfm of indoor air circulated.
