Universal controller
- Universal controllers with integrated control and supervisory functions
- Tested‚ predefined applications (refer to Application Catalog)
- Flexible configuration
- Suited for the controlled variables temperature‚ relative / absolute humidity‚ pressure / differential‚ air
flow rate‚ indoor air quality‚ etc.
- Autonomous sequence controllers with P‚ PI or PID mode
- Functions can be extended (extension modules)
- Clear-text operation with separate operator unit (plug-in type or detached)
- Integrated KNX bus communication
- No commissioning tool required
Extension modules complement the Synco 700 universal controllers and offer extra functions. The
extension modules are attached to the controller. Full operation from commissioning to enduser oper-
ation via the operator unit.
Available extension modules:
- 1 universal module RMZ785
- 2 universal modules RMZ787
- 2 universal modules RMZ788
Total maximal 4 extension modules per RMU7..B can be connected.
Available operator units:
- Plug-in type operator unit RMZ790
- Detached operator unit RMZ791
- Bus operating unit RMZ792
