JUNG KNX Continuous Room Temperature Controller with Integrated Bus Coupler, LS-design, Alpine White LS2178WW

The JUNG KNX continuous room temperature controller with integrated bus coupler delivers precise, energy-efficient climate management for KNX building automation systems. Its continuous PI control algorithm ensures stable and accurate temperature regulation for both heating and cooling applications, while the integrated bus coupler simplifies installation by eliminating the need for an external coupling unit.

Advantages

This controller stands out with its versatile control functions, supporting continuous (0-100%), switching (2-point, PWM, 3-point), and fan coil control. The backlit LCD display provides clear visibility of actual temperature, setpoint, operating mode, and fan stage. Two binary inputs allow integration of window contacts or presence detectors, enhancing energy savings and comfort. The controller supports four operating modes—Comfort, Standby, Night, and Frost Protection—and can be configured via ETS software for flexible adaptation to project requirements.

Suitable for

• Residential and commercial buildings with KNX bus systems
• Heating and cooling control in individual rooms
• Integration with fan coil units (3-stage or continuous)
