Up to 150 units are connectable (including the interlocked units) *2
By connecting three PAC-YG50ECA Expansion controllers (sold separately), a maximum of 150
units of equipments can be controlled. Each DIDO controller (PAC-YG66DCA) contact counts as
one unit.*4

• Number of indoor units that can be interlocked with a LOSSNAY unit: 16
The ON/OFF operation can be performed as a collective, per group, or per block.
The switch operation for the operation mode setting can be performed as a collective, per group,
per block, per floor, or per building. (Available modes depend on the model of indoor units.)

Vertical air flow directions (5 directions), auto setting, and swing setting can be changed collectively,
or for each group or block of indoor units. (Available air flow directions depend on the model. [5 air
flow directions and AUTO] are available only on the models that support those settings.
The fan mode of HWHP (CAHV) units can be switched between Normal and Snow.
Interlocked LOSSNAY units (if any) can be operated (at High or Low) or stopped collectively or for
each group or block of indoor units. (Ventilation mode cannot be selected for the interlocked
LOSSNAY units.)
Group is the smallest unit to which a weekly schedule can be assigned. The same schedule can be
applied collectively, or to each group, groups in a block, or groups on a floor.
• Up to 24 events can be scheduled for each day.
• "ON/OFF", "Operation mode", "Temperature Setting", "Fan Speed Setting", "Vane Setting", and
"Prohibition of operation from local remote controller" can be timer-controlled.
If a license is registered
• Five types of weekly schedule patterns are available.
• Five operation patterns (A-E) can be set for each year, up to 50 days can be allocated to each
pattern.
• When Optimized startup schedule is set, the operation starts so that the preset temperature is
reached at the preset time. (Applicable to indoor units only)
Schedule settings can be Available or Not Available for each group, block, floor, or for all units
collectively.
Operation of certain functions from the local remote controllers can be prohibited collectively or for
each group or blocks of indoor units.
(Applicable functions: ON/OFF, operation mode, temperature setting, filter sign, Water circuit sign
(Air To Water (PWFY)))
Filter sign can be reset for each group or block of indoor units.
Water circuit sign (Air To Water (PWFY)) can be reset for each group or block of indoor units.
