The heat pump is now numbered (HP2). When you press OK, (HP1 and HP2)* disappears and the row "Current address/New address" will go dark. *In this example, we have assumed that the heat pump is called HP1, which is the factory default. If the heat pump has already been renumbered, then select this number instead.
- Page 29 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.
