This overall system description here would help home automation enthusiast's get a good view of our design philosophies and architectures of Hybrid Home Automation system.

HCU is the heart of a system. The essential part of HCU is a powerful microcontroller as well as non-volatile data storage, which allows very precise processing of the control and communication. Flash memory technology makes it able to keep the control structure and recognize commands precisely.

	Power Requirements:		12 VDC (Transformer included to convert from 220 VAC)
	Cable Length:		1,000 Meters (maximum)
	Communication:		Hybrid Protocol (proprietary)
	Ambient Operating Temperature:		20°C to 60°C

PCU is the center of load actuators. The essential part of PCU is and integrated power module or IPM for short. PCU could be adapted for using in single phase or three phase electrical system. There are standard 8 IPM modules and expandable to 16 modules or any size vary from application to application. IPM could detect current flow through load and feedback this information to HCU so system always know every load status.

	Power Requirements:		220 VAC 50 Hz
	Maximum Load:		10 Amps max (Resistive/Inductive Load)
	Load Channel:		8 Channel (expandable to 16 channel maximum)
	Ambient Operating Temperature:		20°C to 60°C

Hybrid Switch Panel acts as keyboard or mouse of HCU. The essential part is a small microcontroller, which allows very precise processing of the control and communication. Switch panel control board, accepts NO contact type input from standard switch module of any manufacturers. Besides, it could reflect load status by red LED lits when load is on and dark when load is off.

	Power Requirements:		12 VDC 100 mA max (derived from Hybrid bus)
	Switch Cover Plate:		All types of switch cover plate ranges from Bticino, Legrand, Haco, etc. brands
	Control Funtion:		On/Off, Dimmer, Toggle and Scene Control
	Ambient Operating Temperature:		20°C to 60°C
