RFTF - Modbus
The display value depends on the set unit system.
By Default, the first lines indicate the following
measurements with the corresponding units
cyclically and consecutively:
Temperature - Relative humidity
The Modbus interface can be used to program an
alternative output variable instead of the standard
display.
In this case, the first line indicates the value and index
while the second line indicates the corresponding unit
statically. The index identifies the display type:
Index 1 = temperature
Index 2 = setpoint potentiometer
Index 3 = dew point
Index 4 = relative humidity
Index 5 = absolute humidity
Index 6 = mixture ratio
Index 7 = enthalpy
The Modbus interface allows the display
to be individually configured,
both in the 7 and 14 segment range and
in the dot-matrix range.
