Daikin Applied Air Handling Systems Offer Advanced Controls with Open Choices™ Integration Many Daikin Applied air handling systems are equipped with factory-mounted MicroTech® III unit controls for optimized performance. Optional Open Choices communication modules allow easy integration with your building automation system using BACnet® or LonWorks® networks.

Open Choices Advantages• Easy, low cost integration into most building automation

systems without expensive gateway panels.• Comprehensive unit control and status information

available with either BACnet or LonWorks. See typical data points list on reverse.

• SimplifiedBASintegrationbecausenetworkparametersare displayed in the unit controller Service menu.

• Save and Restore feature reduces service time and costfor software upgrades.

• FlexiblealarmnotificationandprioritizationwithIntrinsic Alarm Management (BACnet).

Advanced Control Strategies Optimize Comfort and Energy SavingsBuilding Static Pressure Control for whole building or lab pressurization – positive or negative.

Minimum Ventilation Air Volume to consistently maintain the outdoor air requirements of ASHRAE 62 for ventilation and indoor air quality.

Timed Tenant Override for the extended, off-hours comfort flexibilityrequiredintoday’sbuildings.

Variable Air Volume or Constant Volume Control capabilitiesthatcanbecustomizedtospecificneeds.

Night Setback and Setup to take advantage of outdoor air for free cooling to reduce energy costs.
