The iQ Drive
®
heat pump system features modulating compressor
technology and variable speed indoor and outdoor fan motors.
This system is controlled from a two stage cooling and heating heat
pump thermostat. The system has the capability of adding up to
18% of an additional cooling above the rated capacity. The system
has de-humidification capabilities from the thermostat or duct
mounted humidistat.
iQ Drive: Inverter driven Samsung rotary compressor provides five ca-
pacities in modulating operation from a two stage thermostat.
• Interfacecontrolboard:Two digit LED provides system operation, status
and diagnostic troubleshooting information.
- Utilizes a NORDYNE: patented capacity control algorithm
to select the optimum system capacity level.
- System Protection: Internal controls monitor system
operation to protect the inverter drive and compressor.
- Cooling operating temperature range: 50 °F to 125 °F
- Locks out heating: below 0 °F.
- Adaptive demand defrost: Provides additional energy
savings in heating by defrosting only when necessary.
- Five Minute Restart Time Delay: When the unit shuts
down, a delay keeps the unit from restarting,eliminating the highest
cause for compressor failure.
• Suction Accumulator: Protection from liquid flood back and future
compressor failures.
• R-410A Refrigerant: Environmentally friendly non-ozone depleting
refrigerant.
• CompressorandComponentAccess:Designed to make servicing easier
for the contractor, hinge access panels are provided to all controls and
the compressor.
• HighEfciencywiththelowSoundLevels:Up to 19 SEER with sound
ratings of 59-73 depending upon operating conditions.
• CompressorSoundBlanket:Engineered to significantly reduce unwanted
compressor noise.
• VariableSpeedCondenserMotorandSwept-WingFanBlade: A heavy
duty brushless DC motor for long lasting reliability and engineered to
provide quiet operation. Requires no maintenance and is completely
protected from rain and snow.
• CommonSuctionServicePort:This port allows the contractor to read the
suction pressure in all modes of operation without removing any panels,
saving time and increasing serviceability.
• Dischargemufer:Reduces compressor noise and vibration.
• HighPressureSwitch:Protects against abnormally high system pressures.
Auto-reset feature prevents nuisance service visits.
• LowPressureSwitch:Protects against loss of system refrigerant charge.
• LiquidLineFilterDrier:Included with unit, field installed.
• CopperTube/AluminumFinCoils: outdoor coils are designed to optimize
heat transfer, and increase durability and reliability.
• LouveredCondenserGuard:Durable metal guard protects the coil from
yard hazards and extreme weather.
• CompositeBasePan:Absorbs sound and is corrosion resistant. Composite
pan is also stronger and lighter than steel.
• Designedusinggalvanizedsteel: with a polyester urethane coat finish. The
950 hour salt spray finish resists corrosion 50% better than comparable
units.
• OnePieceTop/Orice: Designed for maximum airflow and quiet operation.
• RemovableTop GrilleAssembly: Allows ease of service from the top
without disconnecting fan motor leads.
