Modular heating controller with integrated control and supervisory functions for:

• Up to 6 boilers, multistage or modulating burners
• Precontrol, heating circuit
• Tested, predefined applications (refer to Application Catalog)
• Flexible configuration
• Clear-text operation with separate operator unit (plug-in type or detached)
• Integrated KNX bus communication
• No commissioning tool required

The RMK770-1 supports the languages: English, German, French, Italian, Spanish, Portuguese, Dutch, Danish, Finnish, Norwegian, Swedish, Polish, Czech, Hungarian, Russian, Slovak, Bulgarian, Greek, Romanian, Slovenian, Serbian, Croatian, Turkish.

Extension modules complement the boiler sequence 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:

• 3 universal modules RMZ785
• 3 universal modules RMZ787
• 3 universal modules RMZ788
• 3 universal modules RMZ789

A total of 3 extension modules can simultaneously be used with the boiler sequence controller.
