Note: Some values will be rounded off to fit in the four-character display. Full values can be read with Modbus. All temperature parame-
ters are in °F through Modbus.
* 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.
