Product Name(s): Hawki Advanced
Product Description: Hawki is an application-specific, fixed 31 I/O, configurable, secondary controller intended for general AHU control. All inputs and outputs are dedicated to specific sensors and actuators common to AHU applications. Flexible to change.
Product Application(s): The Hawki provides control strategies for a variety of common constant volume and VAV AHU, Multizone, Dual Duct configurations. Configurations include economizer, static and volume fan-tracking, scheduling, humidification and dehumidification, and a variety of setback and recovery control options.

Programming Method(s) Controllers are shipped pre-programmed for a variety of common AHU sequences and allow parameter and setpoint input by the user. Custom programs are supported, and are typically provided by Novar-trained representatives prior to shipping.
Resident vs Non-Resident Program Execution Program remains resident in controller.
Resident/Supervisory. This controller supervises the scheduling of other controllers.
Resident/Stand Alone. This controller contains its own schedule.
Non-Resident. This controller is dependent upon another controller for its schedule.
None. This controller has no scheduling features.
Other Information not provided
