31.2.2 Overview of configuration diagrams
See the configuration diagram for assignment of inputs and outputs.
Basic configuration
Configuration Function
Plant type  Basic type A: Room temperature ventilation controller (sequence controller 1 is a room temperature
controller, room/supply air temperature cascade controller or supply air temp controller)
 Basic type P: Supply air temperature controller, demand-controlled (sequence controller 1 is supply air
temperature controller)
 Basic type C: Flow temperature controller, demand-dependent (sequence controller 1 is a demand-
dependent chilled water flow temperature controller)
 Basic type U: Universal controller (sequence controller 1 is a universal controller)
 A01…A05: Select a programmed application (activate configuration stored in the controller)
 RMZ785
 RMZ787(1), (2)
 RMZ788(1), (2)
 Add further inputs and outputs with extension modules RMZ785, RMZ787, and RMZ788; controller
functions can be configured to these inputs/outputs
 Specify which modules are connected to the controller in which order (position); max 4 modules

Enter input identifier
 Units:
°C, %, g / kg, kJ /kg, W / m², m / s, bar, mbar, Pa, ppm, Universal
000.0 (display with one decimal place), Universal 0000 (display
without decimal place).
The unit is only required for presentation on the display. The unit
presents all unit-dependent settings (e.g. P-bands) on the unit.
Sensors for °C:
LG-Ni1000, 2xLG-Ni1000 (averaging), T1, Pt1000, DC 0…10 V,
all other units DC 0…10 V, adjustable range
 Digital (input for potential-free contacts)
 Special identifiers:
Room temperature, Outside temperature, Extract air temperature,
Supply air temperature, Frost protection, Remote setpoint
adjuster, Pulse.
With the special identifiers, internal connections are taken directly
from the controller
 A name can be assigned to each input

OT
Outside temperature Outside temperature, sensor as described under "Sensors for °C", for
the following functions:
 Summer/winter compensation
 Sequence locking acc to OT
 Pump on at low outside temperatures
 Locking of fan speed 2 at low outside temperatures
 Max limitation of the outside air damper at low outside
temperatures
