INTRODUCTION

The iQ Drive® heat pump system features modulating compressor technology and variable speed indoor and outdoor fan motors. This system is compatible with any two-stage heating/cooling heat pump thermostat and has the capability of adding up to 18% of additional cooling/ heating above the rated capacity.

When paired with a B64 air handler, this system utilizes de-humidification capabilities from the thermostat or duct mount humidistat.

FEATURES and BENEFITS

iQ Drive: Inverter driven Samsung rotary compressor provides five capacities in modulating operation from a two stage thermostat.
Interface control board: Two digit LED provides system operation, status and diagnostic troubleshooting information.
System Control: Utilizes a 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 heat pump 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.
Compressor and Component Access: Designed to make servicing easier for the contractor, hinged access panels are provided to all controls and the compressor.
High Efficiency with Low Sound Levels: Up to 17+ SEER2 with sound ratings of 58-73, 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 muffler: 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.
Composite Base Pan: Composite is stronger and lighter than steel, but sound absorbent and corrosion resistant.
Designed using galvanized steel: With a polyester urethane coat finish, it passes 950 hours of salt spray per ASTM Std. B117.
One Piece Top/Orifice: Designed for maximum airflow and quiet operation.
Removable Top Grille Assembly: Allows ease of service from the top without disconnecting fan motor leads.
Servicer-Friendly Jacket: Side panels can be easily removed and replaced without removing the top grill.
