Function description When using VAV controllers, a distinction between operating and OEM parameters must be made. Operating parameters are being used during the runtime of a VAV controller, whereas OEM Parameters overwrite the operating parametrers in case of a full reset. OEM parameteres can only be changed when the access level “OEM” is activated.

Mass configuration with change of selected parameters in the target device ENTER → Step 1: The mass configuration mode can (temporarily) be left after upload of the configuration: Selected parameters can then be changed. ENTER → Step 2: After making the desired changes, mass configuration can be resumed with the original configuration; or the changed configuration can be made the new “template“ configuration by newly activating “mass configuration“.
