Serial connection of several iVent 8A ventilation control panels
Options without using the Service Port Software
4. Superior control with wind and rain detector and sensors, taking into consideration pre-set parameters,
such as stroke limitation or activation time
With this option one iVent ventilation control panel is set to Mastermode in the configuration; this means that all OPEN
and CLOSED commands, including stroke limitation or activation times, for the sensors, switches and/or wind and rain
detectors connected to the master control panel (iVent 8A 1) are forwarded to the following iVent 8A ventilation control
panel (slave).
Service Port Software Settings
Configuration of the iVent 8A ventilation control panels via the Service Port Software is different for the master control
panel, as compared with the other control panels. The master control panel should be set to "Mastermode 1" via the
"Superior" selection box. All other control panels should be set to "Forward superior contact input".
