3 Philosophy of basic types
Four basic types are available for the RMU7..B. They differ by:
 Field of use
Ventilation
Primary air handling
Chilled water handling
Universal
 Operating mode
Switch ON/OFF by room operating mode
Demand-dependent by KNX signal
 Control
For room temperature
To demand-dependent setpoints by KNX signal
By a freely selectable, universal measured value
The suitable basic type must be selected for an application.
Short characteristics:
 Basic type A, ventilation controller
Typical field of use: Control of an air handling plant
 Basic type P, primary air handling
Typical field of use: Demand-dependent control of an air handling plant with VAV
individual room control
 Basic type C, chilled water treatment
Typical field of use: Demand-dependent control of a chilled water treatment
 Basic type U, universal controller
Typical field of use: Control to a flow temperature setpoint (universal measured
value)
3.1 Basic type A, ventilation controller

Operating mode: Switch ON/OFF by room operating mode.
The plant is switched on and off by its own time switch.
The controller operates with room operating modes Comfort, Precomfort, Economy
and Protective Mode.
Use of Controller 1: For room temperature.
Controller can be used as a cascade or constant temperature controller.
Fans:
Fan control for single-speed, 2-speed or speed-controlled fans.
Example: Room / supply
air temperature cascade
control
