communication status between the IDU and
wired controller any more. Commissioning
can be performed on the IDU without
configuring the wired controller.
——
This function is valid after step 9. For
example, if receiving a pausing engineering
commissioning signal during the process of
"10. Pre-startup ODU valve status judging
phase" in step 11, the system will restore
the completion phase of "9. Pre-startup
refrigerant judging phase" in step 10.

Re-commissioning is not required. The
number of outdoor and IDUs is memorized.
Addresses of outdoor and IDUs are all
cleared. All the other function settings are
cleared.
