Switch group type 9 is used for
verification from switch group type 7 or switch group type 8, switch group type 9 would only be necessary for redundancy in verifying the
state of the fan. For example, if switch group type 7 is used instead of switch group type 8, the
the monitor module is activated and the
types 7 or 8 also saves the use of an additional monitor module. Switch group type 9 would use two monitor modules to provide the same
verification as types 7 or 8.
