1.12 Onsite Settings

In the case of a multi system, all onsite settings should be made on the master unit. Settings
made on sub units are invalid.
The outdoor unit to which the indoor unit transmission wire are connected is the master unit,
and all other units are sub units.
1.12.1 Onsite Settings With the Power Off
If the COOL/HEAT selector was connected to the outdoor unit in "1-7 Field Wiring", set the dip
switch (DS1) on the outdoor unit PC-board (A1P) to "ON" (it is set to "OFF" when shipped from
the factory).
For the position of the dip switch (DS1), see the "Service Precautions" label (see at right) which
is attached to the EL. COMPO. BOX lid.
Never perform with the power on.
There is a serious risk of electric shock if any live part is touched.
1.12.2 Onsite Settings with the Power On
Use the push button switches (BS1 through BS5) on the outdoor unit PC-board (A1P) to make
the necessary onsite settings.
See the "Service Precautions" label on the EL. CONPO. BOX lid for details on the positions and
operating method of the push button switches and on the onsite setting.
Make sure to record the setting on the accessory "REQUEST FOR THE INDICATION" label.
Use an insulated rod to operate the push buttons via the inspection door of EL. COMPO. BOX
There is a risk of electric shock if you touch any live parts, since this operation must be
performed with the power on.
