Note: Some values will be rounded off to fit in the four-character display. Full values can be read with Modbus. All temperature pa-
rameters through Modbus are in °F, by default. Writing to register 18 will toggle between °F and °C.
* 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-_ _ _ _- _ _ _ _ ).
