* OC_OCCUPIED and OC_UNOCCUPIED commands will
always have full authority over the local occupancy routines
of the thermostat may they be a local input or a PIR cover.
** OC_NUL command will release the thermostat to use its
own internal occupancy routine driven from one of the digital
input or a PIR cover installed on board.
