What You Should Know before Use

Z Suction temperature display

When an indoor unit is running, the suction temperature for the displayed indoor unit is displayed.

Less than 0°C : --°C

49°C or higher : Displayed as 49°C

Z ALL / GROUP / ONE setting

the running state of the indoor unit currently being displayed.

When GROUP is set : The various settings can be made for one or more groups. The display shows the run

ning state of the indoor unit with the smallest number in the group.

When ONE is set : The various settings can be made for individual units. The display shows the running

state of the indoor unit currently being displayed.

Z 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.

Z 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) are held regardless of the duration of the power failure.

The current time and day of the week are held for power failures of up to 48 hours. When the power is recovered

after a power failure for more than 48 hours, the display becomes “--:--”, so please reset the time and date.
