ABB TB/U12-CG Tenton® KNX Control Element 12-gang with CO2, Temp & Humidity Sensor

Description

Introduction

The ABB TB/U12-CG (Order Code: 2CKA006300A1645) is a high-functionality 12-gang room control element from the ABB Tenton® series, specifically engineered for advanced room automation within KNX smart building networks. Designed to unify multiple control functions into a single sleek interface, it allows intuitive operation of lighting, sun protection blinds, heating/cooling systems, and customizable scene settings across modern interior spaces. This device is part of our KNX panel products range.

Featuring integrated environmental sensors for temperature, relative humidity, and CO2 concentrations, the TB/U12-CG serves as an ideal central controller for indoor air quality and room climate regulation. Its built-in room temperature controller (RTC) processes environmental data to optimize HVAC systems, while an integrated bus coupler enables direct connection to KNX Twisted Pair networks without requiring external coupling components or auxiliary power.

Key Features

• 12 freely programmable control push-buttons for multi-function KNX operation.
• Integrated CO2 sensor, relative humidity sensor, and ambient temperature sensor.
• Built-in room temperature controller (RTC) for managing heating and cooling systems.
• Supports switching, dimming, shutter/blind control, value sending, and scene storage/recall.
• Integrated KNX bus coupler for direct line connection to KNX TP networks.
• Clean, modern ABB Tenton® design suitable for flush-mounted installation.
• Powered directly by the KNX bus line operating at 21 to 32 V DC.

Benefits

• Comprehensive Multi-Function Control: Unifies switching, dimming, blind/shutter control, value sending, and scene management into a single 12-gang interface.
• Integrated Environmental Monitoring: Built-in CO2, relative humidity, and ambient temperature sensors reduce the need for separate wall-mounted sensor units.
• Optimized Room Climate Management: Onboard room temperature controller (RTC) regulates heating and cooling circuits to maximize occupant comfort and energy efficiency.
• Simplified Installation: Features an integrated KNX bus coupler for direct connection to KNX TP lines without external auxiliary power supplies.
• Visual Operational Feedback: Programmable push-buttons with status and orientation LEDs deliver clear visual indicators in any lighting condition.
