Checking the Central Control Addresses and Operating the Units that are Controlled by the Schedule
Timer
The schedule timer communicates with the indoor units to check which central control addresses can be controlled with the cur-
rent timer control. The schedule timer can then be used to start and stop these units.
(1) Press and hold the schedule timer button, button, and CLEAR button for 4 seconds or longer. “Ad-(central
control address)” appears in sequence, blinking.
(2) Use the GROUP button in the area to display the blinking central control addresses in sequential order. In this way, it is
possible to check which central control addresses in the displayed timer group can be operated by the timer.
(3) With the selected timer group displayed, press the timer button. Each time the button is pressed the indoor units
in the displayed timer group start or stop. Pressing the button in this mode permits all items (operation start/stop,
operation mode, temperature setting items) at the indoor units in the displayed timer group where remote controller prohibit
is in effect.
(4) After checking the addresses and operating the units, press and hold the button for 2 seconds or longer. The sched-
ule timer display returns to the normal display and all controllable indoor units stop.
