• Optional: for regulating 2 independent fan banks separately and independently (ex. different rotation speeds).
• Optional: Ethernet connection (ex. control parameters on a web page, remote assistance from the works, software update, etc.).
• Optional: sends an e-mail to max. 10 users for each alarm event (if the e-mail addresses have been registered in the PLC memory and the system is connected to Ethernet).

Connectivity
Full remote control (over 900 parameters available) through field BUS (standard: MODBUS RS485; on request: LonWorks®, BACnetTM, SNMP, Konnex®).
