In an exemplary embodiment, devices connected together within a zone, including multi-controller configurations can have a default operation such that all loads in the zone are controlled so that no devices or loads in a zone are uncontrolled. For example, a one button switch 30 connected to a two relay controller 20 would control both loads. An occupancy sensor 50, 52 in a specific zone can control all the loads in that zone. If a zone contains an occupancy sensor 50, 52 only, for example where no switches 30 are present, the controller 20 is configured as an auto on/off based on the signal from the occupancy sensor 50, 52. Regardless of an occupancy sensor 50, the first switch station button will control relay one, second button will control relay two. All switch stations 30 connected will follow with the same button configuration (multi-way switching). In an exemplary embodiment, all buttons in excess of the number of loads will not control any loads and the LED will blink three times when pressed to indicate the button has not been configured. To accomplish the default load to button assignment, it is assumed that loads will default to group membership such that relay 1 will be in group 1 and relay 2 will be in group 2 by default. Toggle buttons 32 on the same switch station will default to group association from the top down. Top button will be in group 1, second button will be in group 2, etc. Group associations can be changed by a user, for example through a control point, such as the smart phone app or buttons on the controllers 20.
