Note: Parameters appear in the Operations Page only if activated from the programming page. See page 22 for Operations Page defaults.

Note: Some values will be rounded off to fit in the four-character display. Full values can be read with Modbus. All temperature param-

eters through Modbus are in °F, by default.

* Low register numbers contain the two higher bytes; high register numbers contain the two lower bytes of the four-byte integer. Decimal

precision is implied at three decimal places unless otherwise noted.

** Static set point version only (SD_C-_ _ _ _- _ _ _ _ ).

*** Profiling version only (SD_R-_ _ _ _- _ _ _ _ ).

**** This value multiplied by 100 equals the percent power.
