Product Description
The Lutron H4P5-CE is a centralized control processor for the HomeWorks 4 Series architectural lighting system. As a “P40” class processor, it represents the higher-tier logic engine for legacy HomeWorks installations, capable of managing large residential or light commercial projects. The H4P5-CE coordinates the communication between user interfaces (keypads, sensors) and power modules (dimmers, switches). It stores the system programming, including scenes, conditional logic, and astronomical timeclock events. The “CE” designation confirms it is built for international markets requiring 230V/240V operation and specific regulatory compliance.
Application Fields
This processor is primarily found in high-end luxury residences, boutique hotels, and sophisticated commercial spaces. It serves as the “brain” for integrated lighting control, motorized shading (Sivoia), and temperature management. It is designed to bridge local lighting control with third-party automation systems like Crestron, AMX, or Control4 via its robust serial integration capabilities.

- Origin: USA / Mexico

Operational Precautions
- Power Sequencing: Always ensure the processor is powered down before adding or removing link wiring; hot-swapping communication wires can cause electrical transients that damage the link transceiver chips.
- Link Loading: Do not exceed the maximum number of devices or total wire length specified for each of the 5 links to maintain stable communication and prevent “ghosting” or delayed response times.
- Back-up Battery: The internal lithium battery maintains the system clock and memory during power outages. If the system loses its astronomical timeclock settings after a power cycle, the battery may need replacement.
- Ventilation: Ensure the processor is mounted in a well-ventilated Lutron enclosure; excessive heat buildup within the panel can lead to processor resets or intermittent logic failures.
