Page 3: Bacnet Protocol Implementation Conformance Statement
BACnet Protocol Revision: 12 Product Description: Melink Intelli-Hood is a demand ventilation product which conserves energy for the commercial kitchen industry. It is particularly used in conjunction with VFD’s (Variable Frequency Drives) which control the speed of the kitchen EF (Exhaust Fans) and kitchen MUA (Make-Up Air) units. - Page 4 Page | 3 Standard Object Types Supported: All objects are statically created based upon device configuration. Create object and delete object are not supported. See object list at the end of this document for more information. Analog Value Binary Value ...

Page 6: Device Object Description
Page | 5 Device Object Description This section describes in further detail each of the Device Objects in the Object/Property Support Matrix and a brief description of each object associated with each Device Object type. System Controller The System Controller is the main Device Object for the system. It acts as a virtual BACnet router for the other Device Objects populated on the Intelli-Hood system. - Page 7 Page | 6 Remote On/Off with Enable A combination of the Remote On/Off and the Remote Enable/Disable digital inputs. This acts as a Remote Enable/Disable digital input as described above. However, it also requests that fans start in the associated Hood Groups. 50% Minimum Speed through 100% Minimum Speed A Minimum Speed digital input is a level sensitive input.
- Page 8 Page | 7 External Alert The External Alert digital input is a level sensitive input. This digital input can be used to alert a non-critical failure for equipment that is external to the Intelli-Hood system. If this digital input is active, an “External Alert” message is displayed in the title on the main screen on the Touchpad.
- Page 9 Page | 8 MUA Damper If the Make-Up Air unit has a damper that closes when the Make-Up Air unit is not running, then the damper needs to be opened before the fan should run. A MUA Damper digital output is then used to signal the damper to open. If there is any input which requests an associated Hood Group to turn on its fans (Fans button from either the Touchpad or Auxiliary Touchpad, Schedule, Remote On/Off digital input), then a MUA Damper digital output is energized.
- Page 10 Page | 9 Highest The affected Exhaust Fans and Auxiliary Airflows either run at the calculated fan speed or the percent speed governed by this analog input, whichever is highest. The analog input percentage is added to the calculated fan speed for the Exhaust Fans and Auxiliary Airflows.

Page 11: Exhaust Fans And Auxiliary Airflows
Page | 10 Exhaust Fans and Auxiliary Airflows Each Exhaust Fan and Auxiliary Airflow can be configured to be present on the BACnet interface or not. By default all Exhaust Fans and Auxiliary Airflows are enabled on the BACnet interface and will populate as a separate Device Object with a DNET matching the configured “BACnet DNET”... - Page 12 Page | 11 Output Current The instantaneous output current reading as reported by the VFD. The output current is not available on all VFD models; be sure it is available on your VFD if you would like to monitor this value. Output Energy The reported kWh counter of the VFD.

Page 13: Hood Controllers
Page | 12 Hood Controllers Each Hood Controller houses up to four temperature sensors and one set of optics for temperature and effluent detection. By default there is not a Device Object present for each Hood Controller, but the system can be configured to do so. Below is a list of the Hood Controller Objects. -

Page 15: Getting Started: Pre-Installation Checklist
BACnet settings for you so it is ready when the system is installed. Below is a quick checklist of settings that could be determined prior to installation. Contact Melink prior to installation with the following configuration settings (either fill in by hand or copy details in some other manner) and these can be configured on your Intelli-Hood system prior to installation. - Page 16 If you unsure of how many Exhaust Fans, Auxiliary Airflows or Hood Controllers your system will have, contact Melink and we can let you know how many of each are scheduled to be included in your system. NOTE: Actual number of Exhaust Fans, Auxiliary Airflows, and Hood Controllers is dependent upon the configuration of the Intelli-Hood system.

Page 17: Configuring The Intelli-Hood System
Page | 16 Configuring the Intelli-Hood System There are three different methods in which the user can configure the Intelli-Hood system. It can be configured through the Touchpad, directly over the network using the web-based configuration, or a configuration file can be uploaded through a USB Flash drive. -
Page 18: Configuration Through The Web-Based Configuration
Page | 17 BACnet Configuration through the Touchpad There are system level BACnet configuration settings as well as BACnet configuration settings specific to each Exhaust Fan, Auxiliary Airflow and Hood Controller in the system. This describes how to get to each of these settings through the Touchpad. 1. -

You can also obtain Melink’s copy of the configuration if you need to revert configuration to match how it was configured when it originally shipped. -
Page 20: Networking Setup And Configuration
Page | 19 Networking Setup and Configuration There are a limited number of network configuration parameters for the Intelli-Hood system. This section describes each in detail. Use DHCP Tells the system whether it should use DHCP to obtain an IP address or not. The Intelli- Hood system defaults to “Yes”. -

Page 23: Common Bacnet Interfacing Use Cases
Page | 22 Common BACnet Interfacing Use Cases This section describes some common use cases for BACnet interaction with the Intelli- Hood system and how to accomplish such tasks. Monitoring Fan Speeds The most common usage is to monitor the fan speed. There are several points that are useful for monitoring fan speed. -
Page 24: Setting Time On The Intelli-Hood System
Page | 23 Setting Time on the Intelli-Hood system There are several Intelli-Hood functions, such as Schedules, that are most useful if the Intelli-Hood system is set for the correct time. The Intelli-Hood system can synchronize time using the Network Time Protocol. However, typical installations will segregate the BACnet network from outside internet access. -
