2.2	HIGH VOLUME, LOW SPEED (HVLS) FAN CONTROLS – GREENHECK TOUCHSCREEN CONTROL
A.	General Description:
1.	High volume, low speed (HVLS) fan controls shall be of the touchscreen type with an enclosure rating of NEMA-1 or better for use in a variety of commercial and industrial applications.
2.	User interface shall consist of a minimum 4 inch, backlit LCD touchscreen that provides fan control, diagnostics, fault history, and menu navigation functionality. 
3.	HVLS controls shall be powered by an included 115 volt power adapter to simplify control setup. 
4.	HVLS controls shall include an externally mounted RJ45 receptacle for plug-and-play connection to HVLS fans via CAT-5e communication cable. Controls may also include an optional, internally mounted circuit board with terminal blocks for connection to a building management system.
5.	HVLS controls shall include the most current firmware version as of the product’s manufacturing date to ensure optimal performance. As a result of continuous development, the manufacturer reserves the right to update controls firmware without notice. 
B.	System Operation:
1.	HVLS controls shall be specifically designed to communicate with one or multiple HVLS fans in any combination of models and sizes via the Modbus RTU communication protocol. Controls shall be capable of operating all connected fans individually with unique speed settings and directions of rotation or in groups with the same speed setting and direction of rotation. Individual or group operation of fans shall be determined by the user during control setup and shall be adjustable after setup is complete. 
2.	HVLS controls shall be capable of adjusting fan speed in predetermined increments (0-10 scale), adjusting direction of rotation (forward or reverse), reporting fan diagnostics, and recording fault history. Controls shall also be capable of dimming the optional, fan-mounted LED light when installed.
3.	HVLS controls shall be capable of providing programmed operation of HVLS fans according to user-defined schedules. Each schedule shall allow operation of the selected HVLS fans during two periods on weekdays (Monday through Friday) and two periods on weekends (Saturday and Sunday). Schedules shall also be capable of being overridden for manual control over fans.
4.	HVLS controls shall include capabilities for password-protected security management with two levels of user access. Low-level user access shall include the ability to turn fans on/off and review alarm conditions. High-level user access shall include full control over all fan functions and settings.
5.	HVLS controls shall be capable of displaying system notifications including (but not limited to) fan status and current alarms on the home page of the user interface for simplified system monitoring.
C.	Options/Accessories:

Specifier Notes: Specify accessories as required for HVLS controls. Delete accessories not required. Consult manufacturer for additional information.
*************************************************************************************************************
1.	BACnet Integration
a.	HVLS controls with optional BACnet integration capability shall include an internally mounted circuit board with terminal blocks for connection to a building management system (BMS). 
b.	HVLS controls shall be designed to communicate with BMS via the BACnet MS/TP communication protocol. 
c.	HVLS controls shall function as a BACnet server, allowing BMS to control fan speed and fan power (on/off), and monitor fan diagnostics and faults.
