for the Heating Actuators
HMT 6 and HMT 12 KNX
for use with heat circulation/distribution systems
to control thermal actuators
1.0 Application and description
The system consists of an HMT 6 or HMT 12 device, the room thermo -
stats as well as the actuators. Both are used in residential applications as
well as various types of service buildings and facilities. Both heating
actuators can optimize the effectiveness of room thermostats used with
thermal actuators. They are suitable for installation in heat circulation/
distribution systems and are equipped with Triacs to ensure silent swit-
ching operation.
Features of HMT 6/12
• Easy wiring of actuators (24 V).
• Connection of up to 13 actuators.
• The unit can be mounted directly to the wall or attached on the
mounting bracket.
• Easy installation by using the unique Spring Clamp Terminals and
color-coding minimizes the installation and setup time tremendously.
• The operation indicators inform the user about the operating voltage
and the condition of the fuse.
