2 They are designed as part of a matched systemusing an AVV air handler or variable speed communicating fur-nace with a CM coil. Both the matched CM coil and AVV airhandler have factory mounted EEVs. The CM coils with factorymounted EEVs can also be matched with the variable speedMVC modular air handlers.*All models in this family are ENERGY STAR listed as part ofa matched Superior Coil Protection An easily removable two-piecesteel extruded louver coil guard protects the tube-in-fin coilfrom debris and physical damage while making access forcoil cleaning quick and simple. Environmentally Friendly Refrigerant The next genera-tion refrigerant R- 410a delivers environmentally friendly per-formance with zero ozone depletion.

3 Durable Finish A high quality powder paint finish rated at1000 hrs. salt spray provides the ultimate protection from cor-rosion and harmful UV rays, ensuring a long-lasting, highquality appearance. Charge Assurance A built-in touch screen instantly dis-plays the system conditions, including the system pressuresand refrigerant charge without the need to attach additionalgauges or sensors. QuietDrive System Features a combination of engi-neered, sound-neutralizing attributes such as a swept-wingfan blade, composite base pan, multi-density compressorcloak and variable capacity operation to reduce sound levelsto that of a mere conversation.

4 ECM Fan Motor Dynamically adjusts speed in sync withthe compressor demand to keep heat exchange in balancewhile minimizing power consumption and sound. Swept Wing Fan A design adapted from aerospace engi-neering provides whisper-quiet operation by allowing air toflow smoothly and efficiently across the fan surface andedges. Composite Base Pan The strong and durable compositebase pan is corrosion resistant while adding strength, absorb-ing sound, and reducing vibration. High-Efficiency Outdoor Coil An aluminum fin and coppertube outdoor coil provide easy cleaning, low restriction to air-flow and efficient heat exchange.

5 Factory Installed Filter-Drier A corrosion resistant, pow-der painted, stainless steel, solid core, bi-directional liquidline filter-drier removes debris and moisture which can beharmful to the system. Climate Set provides pre-configured operating profilesthe installing contractor can select during set-up to fine tunethe system's operation for either Humid, Dry, or Normal cli-mates. Additional fine-tune adjustments are always availableto provide a custom comfort solution. Easy Service Access A large electrical box cover, inde-pendent Charge Assurance access, and a swing open electri-cal box provide superior full corner access to the inside of theunit for maintenance or service.

6 Dual Fuel Ready Using the Affinity Hx thermostat, theYZV will work seamlessly with an 80 or 90% communicatinggas furnace to provide the ultimate year round dual fuel com-fort Controls Unitary Products System Protection All YZV heat pumps have a factoryinstalled suction accumulator to protect the system fromanomalous occurrences. Each system contains high and lowpressure transducers which constantly monitor system per-formance and can alert the consumer or contractor systemconcerns or alerts. EEV Controls All indoor coils, whether in the cased CM coilor in the AVV air handler, have factory installed EEVs (Elec-tronic Expansion Valves).

7 The YZV outdoor units also employan EEV to precisely control refrigerant flow, optimizing capac-ity and efficiency. Communications Capable Requiring only 3 thermostatwires between the outdoor and indoor units, the communicat-ing system provides self-commissioning on start-up as wellas the ability to check system status at the outdoor unit, ther-mostat, or remotely using the designated App. Advanced System Control The proprietary Wi-Fi Hx thermostat interface is an integral part of this innovative sys-tem design. Using the Consumer App, consumers can moni-tor and adjust their system from anywhere in the world usinga smart device.

8 Contractors can use the Service App (withhomeowner permission), to monitor the system remotely andmake adjustments as needed. The system can be configuredto provide alerts for emerging issues as well as items thatrequire immediate attention. Variable Capacity Inverter Controlled Scroll Compressor Constantly monitors and dynamically adjusts systemcapacity in precise increments as necessary to closely meetthe comfort demands of the conditioned space. Premium System Warranty* Limited lifetime compressorwarranty when registered online within 90 days of installation. Agency Listed Safety certified by CSA to UL 1995 / Performance certified to ANSI/AHRI Standard 210/240in accordance with the Unitary Small Equipment OF SECTIONSDESCRIPTION.
