06-062 Mini ECO-i II for Technibel
Setting the main and sub remote controllers
1. Set one of the 2 connected remote controllers as the main remote controller.
2. On the other remote controller (sub-remote controller), switch the remote controller address connector on the
rear of the remote controller PCB from Main to Sub. When the connector has been switched, the remote con-
troller will function as the sub-remote controller.
The sub-remote controller will also operate when connected to the indoor unit (indoor unit 2 or 3).
NOTE
Cautions on group control
G
Group control within the same refrigerant tub-
ing system is recommended.
[Tubing system which is NOT recommended]
Tubing
system 2
3
<Example 1> In the MULTISET system, group control
extending over tubing systems becomes
impossible to set, which means the
indoor units cannot operate.
While Group 4 is in heating operation, if later Group 3
begins cooling operation, indoor units 1, 2 of Group 3
can be operated, but the indoor units 3-6 of Group 4
cannot operate.
