WARNING: The fan controllers contain high voltage capacitors that take time to discharge after removal of mains supply.
Before working on the fan controller, ensure isolation of mains supply from line inputs at the fan controller’s disconnect if
installed. Wait three (3) minutes for capacitors to discharge to safe voltage levels. Failure to do so may result in personal
injury or death. Darkened display LEDs are not an indication of safe voltage levels.
The following additional parameter changes are required for proper operation:
