The CBE PC 210 Control Panel represents the heart of your leisure vehicle's electrical management system, offering microprocessor-controlled monitoring and control through a compact 2.9" graphic LCD display with 12-colour backlighting. This sophisticated unit monitors both your vehicle battery (B1) and leisure battery (B2) in real-time, displaying voltage levels both numerically and graphically, whilst simultaneously tracking fresh water tank levels, internal and external temperatures, and waste water status. The capacitive touch button interface eliminates mechanical switches entirely, providing a modern, responsive control experience that's built specifically for caravans, motorhomes and campervans.
What sets this panel apart from basic control systems is its integrated battery management features, including an electronic battery separator that automatically parallels your batteries when the engine runs, a save battery function that prevents deep discharge damage by cutting non-essential loads at 10V, and dedicated control for 3-way fridges. The system manages everything from water pumps and lighting groups to external temperature monitoring via optional sensors, all whilst protecting your installation through built-in fuse protection within the connected DS300 distribution box. The PC210 works seamlessly with lead-acid batteries in vehicles with standard alternators (Euro 4 or earlier engines), though modifications allow compatibility with Euro 5/6 smart alternator systems when paired with a suitable battery-to-battery charger.
Installation requires 170mm x 80mm recessed panel mounting space, making it suitable for most caravan and motorhome dashboards without extensive modification. The system operates on 12V DC and comes complete with connection capabilities for electronic fresh water probes (which measure tank levels in 1% increments), screw-type waste water sensors, and temperature sensors with 1.5m and 5m cable options. Worth noting is that this panel is designed exclusively for lead-acid battery systems and isn't compatible with lithium battery installations without significant system changes.

Frequently Asked Questions
The PC210 is designed exclusively for lead-acid leisure battery systems including wet cell and gel batteries. It is not suitable for lithium battery installations without significant system modifications. The panel works with both vehicle battery B1 and leisure battery B2, monitoring voltage levels and managing charging through its electronic battery separator which parallels batteries when engine voltage exceeds 13.5V.
The PC210 is designed for standard alternators found in Euro 4 specification engines or earlier. For vehicles with Euro 5 or Euro 6 smart alternators, the voltage-sensing split charging feature will not work effectively on its own. You will need to disable the built-in split charging and install a separate battery-to-battery DC-DC charger to properly charge your leisure battery from the smart alternator system.
The PC210 includes an electronic battery protection device that automatically disconnects 12V users when the leisure battery voltage drops to 10V. This prevents deep discharge damage that can permanently harm lead-acid batteries. The system cuts power to pumps, lights, awning light and heating whilst maintaining power to the fridge, step and auxiliary outputs connected directly to B2. Users are automatically restored when voltage rises above 13.5V or can be manually reactivated for one minute by pressing the main power button.
The PC210 requires an electronic tank probe for fresh water monitoring, which displays levels in percentage with 1 percent step accuracy both numerically and graphically. Fresh water probes must specify tank height when ordering. The waste water tank uses screw-type probes that trigger a full tank alarm when water reaches the sensor level. Temperature monitoring requires separate internal and external sensor cables available in 1.5 metre and 5 metre lengths. All probes connect to the DS300 distribution box which links to the control panel via a 16-pole connector.
Yes, the PC210 includes user programmable settings accessed by pressing the PROG button for more than 2 seconds. You can calibrate both B1 and B2 voltage readings by up to plus or minus 0.5V in 0.1V increments to match actual battery voltage. The backlight colour is selectable from 12 different colours, LED brightness has three levels (min, medium, max), and you can enable or disable acoustic alarms. Temperature readings can also be calibrated in 0.5 degree Celsius steps for both internal and external sensors.
The panel provides visual and acoustic warnings for multiple conditions. Leisure battery B2 triggers a reserve alarm at 11.5V with one short beep and a discharge alarm at 10.5V with two short beeps. Vehicle battery B1 alarms when voltage drops below 12V. Fresh water tank alarms when level falls below 10 percent and resets at 20 percent. Waste water triggers when reaching the screw sensor. During tank filling, the panel beeps at 75 percent (one short), 85 percent (two short) and 95 percent (one long) to prevent overfilling. All acoustic alarms only sound when the engine is off and can be disabled in user settings.
A complete PC210 system typically includes the LCD control panel, DS300 12V distribution box with protection fuses and relays, cable kit for probes measuring 6 metres, control panel cables measuring 6 metres, and screw probes for waste water tank. Optional components include electronic drinking water tank probes specified by tank height, internal and external temperature sensor cables, and a 230V consumer unit with battery charger if mains charging is required. The DS300 distribution box contains the main relay, 70A battery parallel relay, fridge relay, pump relay and all protection fuses from 3A to 30A depending on circuit.
The electronic separator automatically parallels the vehicle battery B1 and leisure battery B2 when the engine is running, allowing the alternator to charge both batteries simultaneously. On standard alternator systems, the separator activates when ignition is on and vehicle battery voltage exceeds 13.5V, then deactivates when ignition is off or voltage drops below 12.5V. This prevents draining the vehicle battery when the engine is stopped. The DS300 distribution box uses a 70A relay for the parallel connection. Vehicles with smart alternators manufactured from September 2019 onwards have modified circuitry that detects engine running conditions differently.
