Connection Of Remote Control Panel Or Modbus (Version 1.1 / 1.2); Fireplace Protection/System Mode Swith/Rapid Ventilation Switch Input (Version S300) - Salda SMARTY XP Mounting And Installation Instruction

Air Handling unit can be controlled with remote control panel POS8. Remote controller connects with S300 controller via KNX PL-Link interface.
T15:1;2 – terminals of AHU's controller for KNX devices.
Same interface and controller terminals are used for QMX3 room sensors P30, P40 and P70 connection.
Air Handling unit can be connected to the Building Management System via BACnet IP or Modbus (RS485).
BACnet is connected to the T5 connector (RJ45) of S300 controller which has default BACnet settings:
BACnet Vendor Identifier: 7
BACnet Vendor Name: Siemens Building Technologies
Default BACnet/IP port: 47808 (0xBAC0)
Default Device Object Instance number: 1
All S300 devices of the same BACnet system must have different device object instance numbers.
Modbus RTU connects to the T12:1;2;3 terminals (Modbus Slave Port1) of the S300 controller which has default RS485 port1 settings:
Baudrate: 19200 bps
Data: 8 Bit
Parity: Even
Stop bit: 1
Slave address: 1
Figure 8.9.1.
After connection of air quality sensor or remote controller, configuration has to be performed. For more information see section "ACCESSORIES
SETUP (VERSION S300)".
Modbus TCP/IP connection can only be implemented via additional device - MB-Gateway. Controller's Modbus Slave Port1 or Port2 can be used
for Modbus TCP/IP connection (see section "CONNECTION TO WIRING TERMINALS (VERSION S300)" for location of the Port2).
USB connector for S300 controller is used to connect WIFI stick and make controller as WIFI access point to control the unit with smartphone or
tablet using ABT Go application. USB connector can also be used for S300 controller firmware updates.
