Universal controller
• Universal controllers with integrated control and supervisory functions
• Suited for the controlled variables temperature, relative / absolute humidity, pressure / differential, air
ow rate, indoor air quality, etc.
• Autonomous sequence controllers with P, PI or PID mode
• Tested, predened applications (refer to Application Catalog)
• Flexible conguration
• Clear-text operation with separate operator unit (plug-in type or detached)
• Integrated KNX bus communication
• No commissioning tool required
The RMU7..0B-1 supports the languages: English, German, French, Italian, Spanish, Portuguese, Dutch,
Danish, Finnish, Norwegian, Swedish, Polish, Czech, Hungarian, Russian, Slovak, Bulgarian, Greek, Roma-
nian, Slovenian, Serbian, Croatian, Turkish, Chinese.
Extension modules complement the universal controller and offer extra functions. They are attached to
the controller via plug-in connectors. The extension modules do not operate autonomously.
The operation of the device from commissioning to enduser operation can be done via the operator unit.
Available extension modules:
• 1 universal module RMZ785
• 2 universal modules RMZ787
• 2 universal modules RMZ788
A total of 4 extension modules can simultaneously be used with the universal controller.
Available operator units:
• Plug-in type operator unit RMZ790
• Detached operator unit RMZ791
• Bus operating unit RMZ792
