timer. To cancel a registered central control address, use the button 2in the
Setting buttons area to select the timer group, then use the button 3in the
Setting buttons area to select the central control address and press the button 5.
(5) When registration is completed, press the button 6. The schedule timer restarts
automatically and performs initial communications. ( flashes in the display.) The
normal display appears after several minutes, and the manually assigned timer group
settings are confirmed.
• During manual timer group settings, the schedule timer can be used to create up to 8 groups (8
zones), and the central control addresses can be registered up to 64 units in 1 group (1
zone).In addition, one of the central control addresses can be set in multiple timer groups.
(Indoor units of the central control address 33-40 are performed to start/stop and enable/
disable operation according to the programmed operation for both timer group (zone) 1 and 4
to illustrate with reference to the thick frame marking as shown in above setting example of
Fig. 13)
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 current 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 button
for 4 seconds or longer. “ (central control address)” appears in sequence, blinking.
(2) Use the 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 schedule timer display returns to the normal
display and all controllable indoor units stop.
