Communication
Function
ing 1 RU, 1snsr+RU or 2 RU, the interface to the
room unit connection is enabled.
Goes to page with all settings relevant to param-
eterizing room units.
Go to page with temperature inputs.
As a matter of principle, the controller must be
set after parameterization to assume the data.
Function
Status of Modbus communication.
Generally enables internal MODBUS and func-
tion of MODBUS over RS485:
− Internal interface is disabled.
− Internal RS485 interface is master.
− Internal RS485 interface is slave.
Controller address on the RS485 bus.
Go to parameter page for RS485 MODBUS in-
terface.
Go to parameter page for TCP/IP settings.
Go to parameter page for MODBUS interface on
module 1.
Go to parameter page for MODBUS interface on

− Go to parameterization page for MODBUS
interface on module 1.
Function
−
Transmission rate on bus. All participants must
have the same setting.
Parity. All participants must have the same set-
ting.
Number of stop bits. All participants must have
the same setting.
Response telegram delay.
Function
Settings access time for master.
The master must undertake read access within this
period, otherwise an alarm is triggered (this func-
tion is not yet fully implemented).
Internal bus connection for the basis controller:
− No bus terminating resistor.
