Description

CBU-ASR is a Bluetooth controllable, Casambi enabled two-channel 0-10V controller for dimmable LED loads and luminaires. It is powered by an external 12-24 VDC Class 2  power supply.
CBU-ASR can control two channels making it an ideal partner for tunable white (TW) applications. The two channels can be configured also to operate individually. The device also has a control port for an external relay and a sensor input.
CBU-ASR is an ideal partner for power packs with line voltage relays. It is protected against overvoltage, overcurrent, and short circuit situations.
CBU-ASR together with other 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 250 units form automatically an intelligent mesh network. Casambi supports a nearly unlimited number of mesh networks on an installation site.
The Casambi system can be controlled with the Casambi app which can be downloaded free of charge from the Apple App Store and Google Play Store. Other controlling methods are, for example, timers, Casambi enable sensors, such as PIR/occupancy and lux sensors, as well as Casambi Xpress and EnOcean switches.

Range

The range between two CBU-ASR units or between a CBU-ASR and a smartphone can vary a lot depending on obstacles and surrounding material. In open-air, the range between two CBU-ASRs is 200 ft, but surroundings may affect the range, so testing is highly recommended.
Casambi uses mesh network technology so each CBU-ASR 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.

Compatible devices:
iPhone 4S or later
iPad 3 or later
iPod Touch 5th gen or later
Android 4.4 or later devices produced after 2013 with full BT 4.0 support

 Casambi uses mesh network technology so each CBU-ASR acts also as a repeater. Longer ranges can be achieved by using multiple Casambi units.

  1. The range is highly dependant on the surroundings and obstacles, such as walls and building materials.

Installation

CBU-ASR is a UL Listed Open-Type device which means that it will have to be used together with a Class 2 power supply with a maximum output power of 100 VA. The product can be installed outside of a junction box. Make sure to comply with National Electric Code in installation and when selecting installation wires.
The product has one return line which is shared between the two 0-10V outputs, relay control output, and sensor input.
The two 0-10V outputs can be configured for different functions, such as 2 channel tunable white, or 1-2 jointly and individually dimmable channels. The standard configuration when delivered is 2 channel dimming, but the configuration can be changed by the end-user from Casambi App.
Do not connect a typical PCB relay to the Relay output. The connected relay must have a flyback diode in place to protect the CBU-ASR against over-voltage spikes.

Dimming without app

Dimming

  1. Turn lights on from a wall switch.

  2. Quickly flick the wall switch off (max. 1 sec.) and back on.
    The light level starts to increase gradually.

  3. Flick the switch again at the desired dim level.
    The selected level is saved automatically.

  4. If the second flick is not done within 8 sec. the light intensity reaches its maximum level.

  5. Flicking the switch can also be used to switch between predefined scenes.

  • The relay must be protected against inductive over-voltage spikes, i.e. it must have a flyback diode. Do not connect a typical PCB relay without the diode.

Warning

Changes or modifications not expressly approved by Casambi Technologies Oy could void the user’s authority to operate the equipment.
