want to save all heat pump parameters in a docu-
ment that can be opened in any calculation program.
Caution
The file name must be LOG.SET for the climate
unit to read the file.
Visit www.nibe.eu/modbus to read more about
LOG.SET files.
Manual reading
Caution
Manual readout is time consuming and only one
value at a time can be read, max timeout 2,1 s.
The parameter does not have to be included in
the LOG.SET file.
Retrieve a value for the Modbus-master by using the
"Read holding registers" command with the desired
parameter address. Use ModbusManager to see which
parameter address a value has. See section The Modbus
command on page 14 for further information.
Enter the values
Caution
Only one value can be entered at a time. The
parameter does not have to be included in the
LOG.SET file.
By using the "Write multiple registers" command with
the desired parameter address, a value can be updated,
if the heat pump/indoor module permits it. The values
that can be updated are in ModbusManager. See section
The Modbus command on page 14 for more information.
