Error set Address
The heat pump could not be found and numbered.
The heat pump was not what it was supposed to be
called.
No communication with the heat pump.
Check that the heat pump is powered up.
If the address setting fails, the latest heat pump addresses
remain. In this example HP1 and HP2.
Make sure the heat pump is powered up.
Try again with a new actual address.
6.3.3 Good to know when setting an address
When all heat pumps are numbered and energised, they
should be displayed when you press the heat pump symbol
in the menu “Operation data”. If any heat pump does not
appear in the menu (communication with the heat pump
fails) It may be because it has not been numbered as
described above.
If you do not know the name of the heat pump, you can
reset the numbering by using the "Select/Rename Heat
Pump" menu (refer to points 9 and 10 above) to indicate
all possible names of the heat pump, i.e. you select and
confirm HP1 and then HP2 up to HP10 to ensure that the
correct name is given.
Finally, test that the respective heat pump starts via the
"Installer/Service/Function test/Heat pump" menu.
