Manual Addressing for Pipe Detection Example (Non-Zone Setting)
Before performing manual pipe addressing, input a different central control address to every indoor unit through either a wired or a wireless
controller (depending on indoor unit type).
Example: An indoor unit with a central control address of "11” is connected to valve "1" of a heat recovery unit.
• The procedure described above must be performed for all heat recovery unit valves.
• Valves that do not have indoor units connected to them must be addressed with a number that has not been used. (Valves will not work if
the address numbers are the same.)
