MDT temperature controllers – precision and flexibility for KNX systems
MDT temperature controllers are a high-performance solution for precise temperature control in modern KNX systems . They offer maximum flexibility thanks to various mounting options – DIN rail, surface-mounted, or flush-mounted – and are suitable for a wide range of applications in residential buildings, office buildings, and industrial environments. With their precise control and easy integration, they make a significant contribution to energy efficiency and comfort in building automation.
Key features
-
Versatile applications
- Control with 2-point, PI or PWM characteristics , configurable via ETS application.
- Freely definable minimum and maximum temperature limits with frost and heat alarms.
- Automatic switching of operating modes day/night/frost protection via KNX bus.
-
Setpoint specification via MDT KNX push button or visualization (e.g. MDT VisuControl).
-
Control variable output as a 1-bit or byte value directly on the KNX bus.
-
Robust and user-friendly
- Integrated bus coupler for simple and secure KNX connection.
-
Alarm messages when limit values are exceeded for increased safety.
- Memory function for minimum and maximum temperature values.
- Compatible with PT1000 temperature sensors (max. cable length 12 m).
