Busch-Jaeger Room Temperature Controller with CO2 and Humidity Sensor, 6-fold, SBC/U6.0.11-84 (2CKA006330A0009)

This Busch-Jaeger room temperature controller stands out by combining temperature, humidity, and CO2 sensing in a single flush-mounted unit with six independent control channels, enabling precise climate management for demanding building automation projects. Unlike simple thermostats, it uses a non-dispersive infrared (NDIR) sensor for accurate CO2 measurement and a PI control algorithm for stable heating and cooling regulation.

Highlights

• Integrated sensors: temperature, relative humidity, and CO2 concentration
• 6 independent control channels for flexible HVAC applications
• NDIR CO2 sensor with measurement range up to 2000 ppm
• PI control algorithm for efficient heating and cooling
• Flush-mounted design compatible with Busch-Jaeger switch ranges

In daily use

The controller operates on 24 V DC via the SBC bus, making it suitable for smart building installations. It provides dew point calculation, fan control, and presence detection via bus, enhancing comfort and energy efficiency. The device is designed for indoor use with an operating temperature range of 0 °C to +45 °C and relative humidity from 5 % to 95 % (non-condensing).
