Central Remote Controller
(1) Indoor unit address acquisition method setting
0: Line address mode
1: Central control address mode
(2) Central controller ID setting
When using in combination
• When using 2 or more units in combination with this Central Remote
Controller only
Set the Central controller ID numbers for the second and subsequent
units to Central controller ID 2 and subsequent ID numbers.
Example: When using 3 units in combination
1st unit: Central controller ID 1 (initial setting)
2nd unit: Central controller ID 2
3rd unit: Central controller ID 3
• When using in combination with a central control device that supports
TU2C-LINK
Set to Central controller ID 2 or a subsequent ID number so that it does
not overlap with other central control devices.
• When using in combination with a central control device that does not
support TU2C-LINK
Set to "Old controller".
When replacing with a Central Remote Controller that does not support
TU2C-LINK
If only 1 unit is used (no combined use), use the initial settings.
When using more than 1 unit, set according to "When using in combination".
IMPORTANT
• If you set the address acquisition method to "Line address mode", it will take time to obtain the address.
• Do not set the Central controller ID to a value other than the values shown in the list.
• If the setting is incorrect, a communication error may occur.
• Unless using it together with another central control device other than this device, there is no need to set the central
controller ID.
• If there is another central control device (of the U series) other than this device, perform central controller ID setting so that
there is no duplication of ID numbers. If there is any duplication of central controller IDs, the check code S33 will appear.
• If there is another central control device (not of the U series) other than this device, select "Old controller" for the setting.
• If the following settings are changed, turn the power off and then back on for the multi outdoor units after the connected
SMMS-u.
