These ModBus registers are shown as Base 1 (PLC addressing) format. Depending

NOTE:
The ModBus data layout may seem unorganized in this document, for
example 0 to 10V for heat and cool is at register 40040 and 40041 while
the 0 to 10V output for the fan is at register 40068. This is because the
SMART 3000 version II has been made 100% backwards compatible with
the SMART 3000 version I. All the functions added to version 2 of the
SMART 3000 have their ModBus registers at the end of the version 1
SMART 3000 ModBus list.
