Installation Instructions
Split System Air Conditioner
®
The iQ Drive
air conditioner operates as part of a larger intercommunicating system which provides temperature, air fl ow,
and humidity control for a residence or other similarly sized building. This system includes this outdoor unit, the dedicated
iQ controller (thermostat), and an iQ system-compatible indoor unit, typically an air handler with electric strip heat or a
gas furnace. The system will function only if these components are matched and intended for use within this system. A
complete list of compatible equipment by model and serial number is available in NORDYNE document 709031, iQ Field
Wiring Installation Instruction. Accessory equipment which may be used with this system includes humidifi ers, electric or
electronic air cleaners, and U/V (ultraviolet) sterilizing lamps.
Refer to the System Operation section below for a complete description of how to use the various features of the system.
In addition to providing the means for operation, the controller also serves as the means for initial system confi guration and
setup, and it provides a considerable amount of information for troubleshooting the system and diagnosing problems.
