MDT Heating Actuator
The MDT Heating Actuator receives KNX/EIB telegrams and controls up to independent electrical outputs . Each channel
has its own LED indicator.
Each channel supplies up to 4 electrothermic valve drives and can be parameterized individually via ETS3/4.
The channels are controllable with PWM (1-bit) or 1-byte telegrams. The integrated temperature controller manages
the actuating value given by external KNX temperature sensors. The temperature controller offers comfort-, night-, frost
protection- and summer- /winter- operation.
The MDT Heating Actuator detects mains voltage failure and has emergency operation if the cyclic telegram is missing.
Additionally they provide objects for heating request and cyclic movement of the valves.
The MDT Heating Actuator is a modular installation device for ixed installation in dry rooms. It its on DIN 35mm rails in
power distribution boards or closed compact boxes.
For project design and commissioning of the MDT Heating Actuator it is recommended to use the ETS3f/ETS4 or later.
