Lower row of zone buttons have stopped activating

The lower row of zone buttons on the ActronAir LM7 may have stopped activating because the zone board/module is not installed or turned on. According to the manual, if the zone board/module is not installed, the zone setup menu will not function. Ensure that the zone board/module is properly installed and powered on before attempting to activate the zones.
