Deselected MCUs (toggle switch OFF) are shown in normal text (black text on a white background).
Selected MCUs (toggle switch ON) are shown in inverted text (white text on a black background).
The MCU may store up to five sub addresses and locks onto the first valid sub address found. This feature allows
one MCU to be able to respond to a maintenance or spare TransKey (in the event of loss of the primary sub
address TransKey) without ever having to duplicate a TransKey sub address on one site. For example, an MCU
may be programmed to respond to SA, 1, 101, 201, 301, 401, 501.
The Sub Addresses are stored in the MCU primary TransKey.
