﻿During operation of the gateway, the matrix assignments of groups and single devices can be switched over by 1-byte objects. This allows the pre-programmed daytime colour sequences to be switched over individually depending on the application.

*Checkbox selected*: The 1-byte communication object "Daytime colour sequence (CTM) - Switch matrix" is available. According to KNX DPT 17.001, a switchover can be performed by the number of the matrix (1...4) during operation of the gateway.

*Checkbox deselected*: No communication object is available for switching the CTM matrices during operation. The CTM matrix defined by the parameter "After ETS programming operation" always remains effective.
