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. If this occurs, scrolls separate, allowing liquid or contaminants to be worked toward the center and discharged Compressor Crankcase Heater (041, 047, 048, 060 models) • 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 EL17XC1 - 1.5 to 5 Ton Air Conditioner / Page 4 FEATURES COMPRESSOR (continued) Optional Accessories Compressor Crankcase Heater (018, 024, 030, 036, 042 models) • Protects against refrigerant migration that can occur during low ambient operation Compressor Hard Start Kit • Single-phase units are equipped with a PSC compressor motor • This type of motor normally doesn't need a potential relay and start capacitor • For conditions such as low voltage kit may be required to increase the compressor starting torque Compressor Low Ambient Cut -Off Switch • Non-adjustable switch (low ambient cut-out) prevents compressor operation when outdoor temperature is below 35°F CONTROLS Optional Accessories E30 Smart Wi-Fi Thermostat • Wi-Fi enabled, electronic 7-day, universal, multi -stage, programmable, touchscreen thermostat • 3 Heat/2 Cool • Auto -changeover • Controls dehumidification during cooling mode and humidification during heating mode • Offers enhanced capabilities including humidification / dehumidification / dewpoint measurement and control, Humiditrol° control, and equipment maintenance reminders • Easy to read 7 in. color touchscreen (measured diagonally) • LCD display with backlight shows the current and set temperature, time, inside relative humidity, system status (operating mode and schedules) and outside temperature (optional outdoor sensor required) • Smooth Setback Recovery starts system early to achieve setpoint at start of program period • Compressor short -cycle protection (5 minutes) • Up to four separate schedules are available plus Schedule IQTM • One -Touch Away Mode - A quick and easy way to set the cooling and heating setpoints while away • Smart AwayTM - Uses geo-fencing technology to determine when the homeowner is within a predetermined distance from the home to operate the system when leaving, away and arriving • Wi-Fi remote monitoring and adjustment through a home wireless network for desktop PCs, laptops and apps for smartphones or tablets • Smart home automation compatible with Apple HomeKitTM, Amazon Alexa°, Google Assistant and IFTTT • Service Dashboard features online real-time monitoring of installed Lennox° smart thermostats • High Definition Color Display with Subbase, Smart Hub Controller, wallplate (for retrofit installations) furnished for easy installation NOTE - See the Lennox° E30 Smart Wi-Fi Thermostat Product Specifications bulletin for more information Remote Outdoor Temperature Sensor • Used with the Lennox° E30 Smart Wi-Fi Thermostat • When installed outdoors, sensor allows thermostat to display outdoor temperature • Sensor is auto -detected when connected to thermostat NOTE - Sensor is required for the Enhanced Dehumidification Accessory (EDA).
