User Manual

An enthalpy value calculated from temperature and relative humidity is available in
RMS705B (device 1). This value is sent as transmission object via an analog
output and handled by the second device.
Example 3
Note Adjust the value range of the reception terminal (device 2) to the unchangeable
value range of the calculated enthalpy prior to use in device 2. See Section 9.2.1
for the set val
ue range for the enthalpy calculator.
