Universal controllers RMU7x0B
The RMU710B, RMU720B and RMU730B universal controllers (see Data Sheet
N3150) are designed for use in ventilation, air conditioning, chilled water, and
primary plants.
• Universal controllers with integrated control and monitoring functions
• Suitable for the following control variables: Temperature, relative/absolute
humidity, pressure/differential pressure, volumetric air flow, indoor air quality
• Each type of controller provides 5 programmed applications (tested plant types)
• Free configuration of customized applications
• Controller functions can be complemented by extension modules
• Up to 32 universal transmit and reception zones per line for data exchange via
KNX in LTE and S-mode
• KNX bus communication for operation and process information
• Menu-driven commissioning, operation and monitoring of controllers and plant
via the operator unit (cleartext display)
• No commissioning tool required for basic plants (easy configuration)
• Commissioning of complex plants with the OCI700.1 service tool

The universal inputs N.X_ can be configured for use with passive sensors, active
signal sources, and status and pulse signals (see page 28).
The analog outputs N.Y_ and relay outputs N.Q_ are ready configured.
