<Monitor Input>
Wire as explained here following, depending on whether input carries a voltage (VOLT.) or not (NON VOLT.). Make the
VOLT/NON VOLT. setting at the monitor input changeover switch (SS1).
(For Voltage Charged Input)
Set the monitor input changeover switch to VOLT. (Factory setting: VOLT.)

(For Non Voltage Input)
Set the monitor input changeover switch to NON VOLT. (Factory setting: VOLT.)

equipment
Switch the malfunction signal switch (SS3) according to needs (Factory setting: W/O [OFF]). Set the switch to W (ON)
to display errors even if no operation feedback from the indoor unit is available, for example, when power to the indoor
unit is OFF. Together, set the individual switch (SS2) to OFF (ON).
Note:
This switch is ineffective when SS2 is set to ON (OFF).
The centralized control equipment display will change, as shown on the right, depending on the monitor input state
and the malfunction signal switch (SS3) setting.
After switching the centralized control equipment from stop to operation, it will take from 10 to 30 seconds before the
centralized control equipment display will indicate an error.
