Akubela 4-Button KNX Temperature Control Panel with LCD Display

Akubela KXTC-B1B4-EU KNX 4-Button Temperature Control Panel

The Akubela KXTC-B1B4-EU is a bus-powered KNX wall panel that combines room temperature sensing with four physical control buttons and a backlit LCD screen. Designed for integration into KNX/EIB automation networks, it lets occupants adjust setpoints and switch between HVAC modes while giving installers a compact, standards-based device that programs directly through ETS. It is well suited to air conditioning, underfloor heating and ventilation systems that need a simple, reliable wall-mounted interface.

Key Features

• Four-button interface for setpoint adjustment and quick mode changes
• Built-in temperature sensor with high-precision ±0.1°C display accuracy
• LCD screen showing real-time indoor temperature and humidity readings
• Supports multiple HVAC modes, including air conditioning, ventilation and underfloor heating
• Fully bus-powered over KNX/EIB, with low standby power consumption
• Configurable scene recall and delayed value transmission for smoother automation behaviour
• Fits a standard 60mm wall installation box for straightforward retrofitting
• CE and KNX certified for compliance with EU building automation standards
• Programmed and commissioned using the standard KNX ETS tool

Typical Applications

This panel is ideal for residential and light commercial KNX installations where a dedicated room controller is needed alongside touch panels or app-based control. It works well in bedrooms, offices, hotel rooms and meeting spaces where occupants need fast, tactile access to temperature and mode settings without navigating a touchscreen menu. Because it communicates natively over the KNX bus, it integrates cleanly with fan coil actuators, heating valve controllers and other KNX HVAC equipment from Akubela or third-party KNX manufacturers, making it a practical addition to new-build or retrofit smart climate systems.

Frequently Asked Questions

Does this panel need a separate power supply?
No. It draws its operating power directly from the KNX/EIB bus, so no additional mains wiring is required at the panel itself.

Can it control both heating and cooling?
Yes. The panel supports multiple HVAC modes, allowing it to manage air conditioning, ventilation and underfloor heating outputs when linked to compatible KNX actuators.

What tool is used to configure the panel?
Installers commission and configure the panel using standard KNX ETS software, the same tool used across the wider KNX ecosystem.
