5.19 Automatic auto-restart after a blackout
5.19.1
This function requires the presence of a special restart module, which is pre-installed on Indoor Units of
these systems.
As it has already been shown, (see “Section 1: General Information” of this Service Manual), the system is able
to restart automatically with the previous settings before the blackout.
5.19.2 Automatic restart will take place after a 3-minute delay since power supply is restored.
5.19.3 However, “TIMER” and “SLEEP” settings (for HKEU X Multi Liberty Models only) will be cancelled, so they
must be set again by the User when power supply is restored.
5.19.4 In the same way, automatic swinging (“SWING”) of air outlet flaps - if it was active when the blackout
occurred - must be selected again by the User after power supply is restored.
5.18.3 Some examples of operation in case of operation modes’ conflict
a. If one or more Indoor Units are operating in Cooling or Fan mode, and operation in Heating mode is selected
on at least one Indoor Unit of the same system, the Indoor Unit operating in Cooling or Fan mode will get to
stand-by status. System’s Outdoor Unit will start opeating in Heating mode, as Heating mode has always the
priority over the other operation modes.
b. However, if all Indoor Units operating in Heating mode are stopped (OFF), the system’s Indoor Unit(s) in stand-
by (see above) can restart in Cooling or Fan mode.
c. If one or more Indoor Units of system are operating in Heating mode, and operation in Cooling or Fan mode is
selected on at least one Indoor Unit of system, the Indoor Units operating in Heating mode keeps on operating
regurarly, while the other Indoor Units keeps in stand-by. The Outdoor Unit will keep on operating in Heating
mode, as Heating mode has always the priority over the other opeation modes.
d. The above Table shows that Fan mode of one or more Indoor Units is compatible with operation in Cooling
mode of the other Indoor Units; however, Fan mode is not compatible with operation in Heating mode of one or
more Indoor Units of the same system.
