of 48 indoor units in one system. And furthermore, by
combination with SLA-2A-E, the schedule setting for
each group (16 groups at the maximum) becomes

OSwitch the control changeover switch (SW 9) to the
appropriate side considering whether SLA-2A is used
together or the disposition after power outage recovery.
Power outage compensation function is equipped.
ODuring power outage or the power is off, the condition
set by the weekly timer is held. After restoration, the
monitor mode is displayed conforming to the time when
restored.
OSwitching the control changeover switch(SW9-2) to
ON, transmits an operation (stop) command after power
outage recovery using the timer setting mode under
recovery.
When the timer setting mode (as shown in the graph
below) is 1, a stop command is transmitted because the
system is in the stop mode at power outage recovery.
When it is 2, an operation command is transmitted
because the system is in the operation mode at power
outage recovery.
OPay attention that the control changeover switch is set
to OFF at delivery, therefore no operation (stop)
command is sent after power outage recovery.
