When using with the Weekly-Timer, all switch settings except S41-1 must be OFF.
About the Setting Switches
●Complete the switch settings before turning ON the schedule timer power.
::: Continue from the previous section :::
Remote Controller Enable Items Switch (1) (Substitute/Addition Selector)
OFF: (Substitute mode)
All setting contents will be substituted to setting contents using the remote controller disabled item
switches 2, 3 and 4 as opposed to the remote controller enable/disable items in setting presently.
Example: In the case of setting to [Mode 5] during remote controller disabled item (Temperature
setting+ Start/stop mode)
ON: (Addition mode)
Items set to ON using the remote controller disabled item switches 2, 3 and 4 will be added to the
remote controller enable/disable items in the current setting.
Example: In the case of setting to [Mode 5] during remote controller disabled item (Temperature
setting+ Start/stop mode)
Setting Central Control Addresses when using with the Schedule
Timer
●When using the schedule timer, central control addresses setting of the indoor
unit is required.
(If central control address of the indoor unit has not been set, the schedule timer cannot be
used to start and stop these units normally. Therefore, be sure to set the central control
addresses of the indoor unit before turning on the power of the schedule timer.)
(1) Turn on the power of all the indoor units.
(2) Confirm the setting for the system addresses, indoor addresses and group addresses
of all indoor units. If a wrong setting is found, reset the system addresses, indoor
addresses and group addresses correctly.
(3) Perform the address settings that turn off the power of the indoor units.
• Central control address setting using the wired remote controller
<Perform the following procedures, 1 to 5, to all the indoor units>
1. Press and hold the wired remote controller button and button for at least 4
seconds.
2.
Assign the item code (DN) to
using the temperature setting button
/.
3. Set the desired control address (1 to 64) using the timer button / .
4. Press the button.
(Confirm the remote controller indication changes from flashing to fully lit.)
5.
After setting is completed, press the
button and then return the unit to general off status.
(In this case, it will take about 1 minute for normal remote controller operation to resume.)
<Central control address setting using the 64 system central remote controller>
Refer to the [Address switch setting] in the [Installation manual of 64 system central remote
controller] that is supplied to the 64 system central remote controller.
Creating Timer Groups when using the Schedule Timer
●The schedule timer can be used to create up to 8 timer groups (8 zones).
<Setting fixed timer groups (zones)>
●Procedure for making fixed timer group settings (zone)
(1) First, use a 64 system central remote controller 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 (zones) you wish to
create.
(For setting of switches 2 and 3, refer to the [About the Setting Switches] item above.
(3) Finally, turn on the schedule timer power. Initial communications are performed.
( flashes in the display.) The normal display appears after several minutes, and
the timer group settings are confirmed.
<Procedure for making manual timer group settings (zone)>
Manual timer group settings allow central control addresses to be assigned freely within the timer
groups such as the setting example below.
●Procedure for making manual timer group settings (zone)
(1) Turn on (manual settings) S41 setting switches 2 and 3, then turn on the power.
Restart and initial communications are performed. ( flashes in the display.) The
normal display appears after several minutes.
(2) When the normal display appears, press and hold the schedule timer button, the
button, and the button 1for 4 seconds or longer. “ ” appears,
flashing, in the present time display. ( indicates “address” and is the central
address number.)
(3) Use the button 2in the Setting buttons area to select the timer group for
programmed operation. Then use the button 3in the Setting buttons area to
select the central control address to assign and register for that timer group. Press the
button 4to register the selected central control address. (Registered central
control address appears on the [Timer program] display area of the schedule timer.)
(4) To continue registering addresses, repeat step (3). Central control address numbers
will be added to the right side on the [Timer program] display area of the schedule
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.
Installation Work Plan
●Use the wired remote controller to check the unit No. of the indoor units.
(Start the A/C unit with the wired remote controller, then press the remote controller
UNIT SELECT button once to display the unit No. of the master unit.)
