3-3 Switch function of remote ON-OFF switch
SW1
(Switches between
remote ON and OFF.)
w1 After all units start together, if SW2 is turned OFF, each unit can be individually stopped by each remote controller.
w2 After all units stop together, if SW2 is turned OFF, each unit can be individually started by each remote controller.
4. INDIVIDUAL CONTROL BY GROUPING THE REMOTE CONTROLLERS
Grouping the remote controllers allows individual control and central-
ized monitoring of units installed in different places without a special
control board.
Remote control cables are extendable up to 500m. When the cable
length exceeds 12m, use the double-insulated two-care cable such as
Belden 9407. Also, the cable thickness must be No. 22 AWG or above.
When gathering the power ON/OFF switches of air conditioners near
the remote controllers, you should also install the power ON/OFF
switch near each unit to prevent electric trouble during servicing.
