❚ Power failure compensation
This central control has a power failure compensation function. The factory setting is program setting priority.
To give priority to the state before the power failure or to disable power failure compensation, please consult your
dealer.
❚ What power failure compensation is
When the power supply for this central control is recovered after a power failure or the turning the power off,
the power failure compensation circuit automatically sends run signals according to the program settings or
the setting state before the power failure.
There are the following two types of compensation.
1. Priority to program setting
For the Run / Stop state and the set temperature, signals are automatically sent for the program set for the
day on which the power is recovered. For other states (mode, etc.), the signals give priority to the state before
the power failure. (See 2.)
If program for the day on which the power is recovered has not been set before recovery, control after power
recovery uses the states before the power failure. (See 2.)
2. Priority to state before power failure
Signals are automatically for the state of each indoor unit before the power failure.
Indoor units that were running when the power failed resume running.
3. Do nothing after power supply is recovered
After the power is recovered, this central control does not send any signals at all.
Note
The group settings, individual unit settings, program settings, holiday settings, external timer settings, demand
settings, run status (run / stop, operation mode, set temperature, center / remote, remote controller operation
enable / disable, fan speed, louver direction) are held regardless of the duration of the power failure.
