Purpose
Duty rotaon allows cascade management (Periodic turn-based turning on and off) of mulple units in
an air-condioned environment so that overall lifespan of unit can be extended and backup units are
available in the case of malfuncon encountered by running units.
Duty rotaon in YKEA model involves two units connected to one wired remote control, classified as
Main unit (connected to CN-CNT (A) port) and Sub unit (connected to CN-CNT (B) port). Duty rotaon is
managed by a built-in soware in wired remote controller (instead of indoor unit soware). During
normal operaon, unit is controlled by wired remote controller through CN-RMT transmission. During
Duty rotaon, wired remote controller will send signals periodically through CN-CNT (A and B) signals
to indoor unit to turn ON/OFF the units.
