CBU-A2D
Bluetooth controllable 2ch 0-10V/DALI controller
Description
CBU-A2D is a Bluetooth controllable, Casambi enabled 2 channel 0-10V/DALI controller. CBU-A2D has a universal 85277 VAC input voltage range,
CBU-A2D can control one or two 0-10V controllable LED drivers, or it can control a tunable white LED driver with two
0-10V control interfaces. The product can also be congured into a DALI mode where it can be connected to a DALI LED
driver or DALI sensor for presence and/or daylight harvesting functions.
CBU-A2D can be controlled with Casambi app which can be downloaded free of charge from Apple App Store and Google
Play Store.
Dierent Casambi enabled products can be used from a simple one luminaire direct control to a complete and full featured light control system where up to 127 units form automatically an intelligent mesh network.
Installation
Make sure that the mains voltage is switched o when making any connections. Use 0.5-1.5 mm2 solid or stranded conductor electrical wires. Strip the wire 6-7 mm from the end. Insert the wires into the corresponding holes and tighten
the connector screws.
If the connected LED driver cannot be turned o completely from the control interface, an external relay with 12 VDC
coil can be connected to channel 2. Make sure the relay is protected against yback voltage, e.g. do not use a PCB relay
without the yback diode. A suitable xture conguration must be selected in order to control a relay.
CBU-A2D, as any other Casambi product, should not be placed in a metal enclosure or next to large metal structures.
Metal will eectively block radio signals which are crucial to the operation of the product. A thorough connectivity testing
is strongly recommended in the installation site.

Range
The range between two CBU-A2D units or between a CBU-A2D and a smart phone can vary a lot depending on obstacles and surrounding material. In open air the range
between two CBU-A2Ds can be in excess of 200 ft, but if the unit is encapsulated into a metal structure, the range can be only few feet. Therefore, thorough testing is
highly suggested.
Casambi uses mesh network technology so each CBU-A2D acts also as a repeater. When testing the network, it is important to test that each unit can be controlled from
any point of the network covered area.
