TOU Present Season Data
For Present Rate Previous Season, add a value of 1000 to the binary addresses shown for Present Rate.
For Present Rate Self Read X, add a value of 2000 to the binary addresses shown for Present Rate. For
example, to retrieve “Present Rate Previous Season Rate A MWH Total,” take the Present Rate “Rate A
MWH Total” address of 12300–12301, and add 1000: 13300–13301 (3412–3413 Hex).
