PCU Control Unit – central control and monitoring unit for the vehicle's electrical system

The central control and monitoring unit for your on-board electronics – in motorhomes, campers, vans, and boats

The PCU Control Unit is the central control and monitoring unit for all on-board electrical systems – the intelligent heart of your power supply in vehicles and on board. You can control and monitor your entire on-board network via a single, intuitive touch display: battery, tanks, energy flow, and connected devices. Instead of many individual displays, the PCU bundles all functions in one place, giving you complete control over the on-board electronics in your motorhome, camper, van, caravan, or boat.

What the PCU replaces

Instead of separate battery monitors, tank gauges, and control panels, one display takes over complete control and monitoring of your on-board network. This saves space on the control panel, reduces wiring, and makes operation clear – all values and all controls in one place.

Control and monitor on one display

As a central unit, the PCU combines control and monitoring in one device: you keep all values in view and intervene directly – without having to switch between several devices.

Real-time battery monitoring

The PCU provides precise real-time data on battery status, voltage, current flow, and temperature, and reliably monitors your starter battery as well. As a full-fledged battery monitor or battery computer, it shows charge status, consumption, and remaining capacity – compatible with 12-V and 24-V systems and all common battery types.

Tank monitoring for fresh, grey, and black water

The integrated level indicator monitors all tanks and is compatible with the most common sensor systems – ideal for motorhomes, campers, and boats.

Energy management with energy flow display

The integrated energy flow diagram visualizes all sources and consumers in real-time – solar system, charging booster, inverter, and more. You immediately see where the energy comes from, how much is generated, and which consumers are active.

Central device control – refrigerator, heating, air conditioning

Via CI and CAN bus, you control your refrigerator, heating, air conditioning, and other on-board technology directly on the display. Indoor and outdoor temperatures are also displayed.

Easy installation, maximum compatibility

All interfaces are integrated directly into the display – no additional modules needed. In combination with the CONNECT HUB, all sensors are connected centrally, with only a single cable leading to the display. Optionally expandable with the Switching Unit (PSU) for a full-fledged load management system.

Made in Germany – developed and manufactured for continuous use on board.

Areas of application

• Motorhome, Camper & Van: Battery, tanks, and energy centrally in view – ideal for independent travel
• Boat & Yacht: robust on-board monitoring and device control for use on board
• Caravan & Motorhome: all consumers and fill levels on one display

Technical data

Frequently Asked Questions

What is the PCU Control Unit? The central control and monitoring unit for on-board electronics in motorhomes, campers, vans, and boats – battery, tanks, energy flow, and devices on one touch display.

Does the PCU work with 12 V and 24 V? Yes, it is compatible with 12-V and 24-V on-board networks and all common battery types.

Which tanks can the PCU monitor? Fresh, grey, and black water via the integrated level indicator, compatible with the most common tank sensors.

Do I need additional modules? No, all interfaces are integrated into the display. With the CONNECT HUB, sensors are connected centrally.

What is the difference between PCU and a classic battery monitor? A battery monitor only shows battery values. The PCU also monitors tanks and energy flow and controls devices – as a central unit for the entire on-board network.
