Comparing an Energy Saving Lighting Control System with a Full-2Way Lighting Control System
Full-2Way Lighting Control System: Replaces a traditional switch with a centralized control and local controls which are connected through a digital trunk bus, allowing control to be made from both the local site or remotely.
Energy Saving Lighting Control System: A further advancement which incorporates sensors into an energy saving system. Creating a system that can be controlled from local switches, central control and motion sensors.
A more complete definition would be to include safety, lighting, small room fans combined into one system. A concrete example would be a hotel guest room control system.

1. When the guest leaves the room, the lighting and air conditioning will all turn off or will enter energy saving mode.
2. At any time, the central control system can determine the status of the safety, lighting and air conditioning in the room.

A. System Architecture 

1. Multiple touch panels can be used in the same system, not only are the status of the lights shown, but the execution and response is very fast, they are low cost and high reliability.
2. Pattern switches work differently. Unlike in a full-2way system, they do not need an MRS (Main Remote Station) to work, and they don’t require any special programming. They can issue both pattern and group commands independently.
3. Integrates both lighting and safety at the same time on the same touch panel screen.
4. Easy to set up schedule, allowing the end user themselves to make any changes without the need for special software or qualified technician.
5. Can be integrated into third party systems. It communicates the industry standard Modbus protocol, which allows it to be linked (via either RS485 or TCP/IP) to any system that supports it.
6. The touch panels can be uplinked to a network and synchronized with multiple types of devices including PCs, mobile phones or tablets for the purpose of remote control.

Installation, Maintenance and Reliability

1. With a Japanese branded full-2way lighting control system, once the MRS unit containing the CPU fails, then the entire system collapses and all the patterns and groups that have been set needs to be reconfigured. Contrast this with DAE’s system where there is no CPU to worry about, and hence there is no central point of failure.
2. Each of the controller modules in DAE’s line up contains manual control buttons on board that can be used as backup control that can directly control the lights that is connected to its channel. These can also be used after installation for verifying the installation, or for diagnosis and testing during repair.
3. Since there is no need of a unit such as the MRS, then the entry level cost is greatly reduced as this unit is the single most expensive unit when adopting a Japanese branded full-2way lighting control system. Thus even a small establishments such as restaurants, libraries, offices can adopt this system with a small budget.

Lighting Control Modules

1. There is no need for the prohibitively expensive proprietary TR system power supplies that is needed by the Japanese branded full-2way lighting control system.
2. Three forms of controller modules available for every kind of situation: Controllers specially designed for contactor use, controllers with built-in relays, and controllers with external relays.
3. Smart TUs, each controller is equipped with manual control buttons for each lighting channel that it controls, and the auto-learning logic built-in that enables each controller to learn patterns and groups. Which make them easy to configure, test and maintain. They do not need any special device for configuration, and can be done by a non specialized personnel.
4. Smart interactive energy saving control modules:
   Can accept sensors and classic wall switches, they have special energy saving logic built-in. They are inexpensive and easy to maintain.
5. DAE’s lighting control system includes modules for LED dimming, with more channels that those available from competing full-2way lighting control system.
