A Time Pattern Regime (TPR) relates to Settlement Registers on metering systems. Each TPR is associated with a pattern of switching behaviour that defines the times at which the register is operational (i.e. recording energy data).
Switching between TPRs occurs either through fixed "time switches" or dynamically via "Teleswitching instructions" i.e. a radio signal. TPR Ids are assigned to Standard Settlement Configurations IDs.
For further information on Standard Settlement Configurations please see the FAQ relating to it
