CONTROL VIA SUPERVISION WITHOUT USER INTERFACE
As shown in the figure, by inserting the VMF-IO expansion board you can control the fan coils via the VMF-E5 panel or third party
BMS systems without the need for VMF-E4/E2 user interfaces. To ensure the fan coils work properly however, an air probe must
be installed on the machine.
When the VMF-IO expansion is used, systems requiring local TTL networks cannot be managed.
LONWORK SUPERVISION NETWORK
The VMF-E19 control card is designed to be connected with control and/or supervision systems that communicate in LonWork.
For more information about the technical specifications (physical connection, data exchanged, system settings) of the LonWork
protocol, refer to the specific documentation.
