Creating Timer Groups
The schedule timer can be set for 6 time status
changes. These can be used to create up to 8
groups (timer groups). For systems in which
schedule timers are used, set the timer groups to
match the central control addresses of the indoor
units that will be subject to group timer control.
The timer-group settings for the schedule timer
involve assignment of central control addresses.
Therefore, use the system controller (or other
central control device) or wired remote con-
trollers to set the central control addresses of the
indoor units, then make the schedule timer set-
tings.
●
Procedure for making fixed timer group settings (fixed groups)
(1) First, use a different central control device (system controller or other device) or the wired remote controllers to
set the central control addresses, as assigned in the figure above, to the indoor units that will be subject to
group timer control.
(2) Next, use S41 switches 2 and 3 to set the number of timer groups you wish to create.
(3) Finally, turn ON the schedule timer power. Initial communications are performed. (SCAn blinks in the display.)
The normal display appears after several minutes, and the timer group settings are confirmed.
●
Procedure for making manual timer group settings (manual group assignments)
Manual timer group settings allow central control addresses to be assigned freely within the timer groups.
(1) Turn ON S41 setting switches 2 and 3, then turn ON the power. Restart and initial communications are performed.
(SCAn blinks in the display.) The normal display appears after several minutes.
(2) When the normal display appears, press and hold the schedule timer button, the timer button, and the
button for 4 seconds or longer. “Ad-01” appears, blinking, in
the current time display. (Ad indicates “address” and 01 is the central address number.)
(3) Use the button in the area to select the timer group. Then use the button in the area to select
the central control address to assign and register for that timer group. Press the button to register the
selected central control address.
