Functions
Automation stations for HVAC and building control systems.
● System functions (alarming, scheduling, trending, access protection with individually
definable user profiles and categories)
● Freely programmable (close resemblance to CEN standard 11312). All function blocks,
available in libraries, can be graphically connected.
● Engineering and commissioning with the ABT Site Tool using graphical function charts
● BTL tested BACnet communication, in compliance with the BACnet standard including B-
BC profile (Rev. 1.15)
● Generic object viewer for device local data points via an embedded web-based interface
● Wireless connection for engineering and commissioning
● Integration of Modbus data points via RTU
● Direct connection of field devices
Technical and mechanical design
The compact build allows for mounting the devices on a standard rail or a wall.
