BACNET™ MOTORIZED VAV DIFFUSER
INSTALLATION INSTRUCTIONS
Commissioning
The EF-B unit is shipped with default values and will start to operate once power is supplied.
1.
To establish communication, switch dip switch AUTOM 'off' and set the MAC address using the seven dip switches labeled 1
through 64 using standard seven bit addressing (i.e. 1 'on' is 1, 1 'off' and 2 'on' is 2, 1 'on' and 2 'on' is 3, etc...).
2.
Turn on the 24VAC supply power.
3.
Discover ("who is") the EF-B using preferred BACnet software.
4.
Re-assign the Instance Number (ID Number) as required by the specific network. (A random instance number is assigned at
the factory.)
5.
Refer to the EF-B Object List (Form 091.202) and configure the different properties of the EF-B as required by the project.
Power Failure
Objects designated as Configuration are stored in non-volatile memory so that the EF-B diffusers can resume normal operation
when power is restored after failure. See the EF-B Object List (Form 091.202) for a complete list of the Configuration Objects.
Air Density Compensation
Installation at altitudes above 1650ft / 503m requires modified settings for air density effects (see BACnet Object List Form
091.202).
