in that system to either cooling mode or heating mode.
During automatic address setting: When the pins are not connected, the mode is
heating mode.

setting is in progress interrupts automatic address setting.
CHK (2P, white) When these pins are short-circuited, the mode is test run mode. (Test run mode is
(CN45) automatically canceled after 1 hour.) When the pins are released, test run mode is
canceled.
RC (3P, blue) The outdoor unit maintenance remote controller can be connected here to check the
(CN37) alarm details.
RUN (2P, white) Short-circuit these pins and apply a pulse signal to start all indoor units in that system.

STOP (2P, white) Short-circuit these pins and apply a pulse signal to stop all indoor units in that system.
(CN49) (If the pins are left short-circuited, it will not be possible to start operation from the indoor
unit remote controllers.)
