MDT temperature controllers – Precise temperature control for your KNX systems
MDT temperature controllers offer a flexible and reliable solution for temperature control and monitoring in modern KNX systems. With various versions for DIN rail, surface, and flush mounting applications, they enable precise control in residential and commercial projects.
Key features
-
Flexible control concept
- Choice between 2-point, PI and PWM control depending on the application.
- Control via KNX bus or analog inputs for PT1000 sensors (max. 12 m cable length).
- Minimum and maximum value storage for temperature limits.
- Alarm functions in case of exceedance of frost or heat limits.
- Switching of the operating mode (e.g. day/night/frost protection) via KNX bus.
-
Versatile control options
- Setpoint specification via MDT KNX pushbuttons or visualizations such as MDT VisuControl.
- Control variable output as a 1-bit or byte value on the KNX bus.
- Status feedback via HVAC and RHCC status objects.
-
Robust and efficient design
- Suitable for dry indoor areas (protection class IP20).
- Integrated bus coupler for easy integration into KNX systems.
