3-2-3. Operation method of wired remote controller
❑
Press the ON/OFF button of wired remote controller to be on.
At the time, the set installed from A chamber to F chamber is getting on in order with the interval of 2 seconds.
❑

❑
Select breeze/weak/strong/wind auto by pressing the wind volume button.
❑
Adjust the temperature set button to set the desired temperature.
● For reference
❑
The communication between wired remote controller and
indoor unit is made through the synchronization with the out-
put signal of zero cross detect circuit, and when 50Hz power
is used, it has the 50bps transmission speed and when it has
60Hz power it has 60bps transmission speed. The transmis-
sion data between the wired remote controller and indoor unit
is shown as in the figure.
Since the communication data between wired remote controller and indoor unit is consisting of total 10Byte, 2 seconds are required when
using 50Hz power.
❑
For the communicating time with 16 chambers during the normal operation, 32 seconds are required and for the time with 16 chamber
during the reservation operation, 64 seconds are required due to the increase of communicating data.
