As a Modbus TCP/IP gateway, the ISE SMART CONNECT MODBUS VAILLANT offers access to a Vaillant geoTHERM/3 heatpump, as well as to three Vaillant VR60 mixer modules and up to six Vaillant VR90 remote control devices. The established Modbus TCP/IP standard (e.g. Schneider SmartStruxure, Fidelix) enables the convenient integration of Vaillant heatpumps into the building technology.
