Note 1
Note 1: Set LGH-F300 to F600 types to the OFF setting, and LGH-F1200 type to the ON setting. The system
will not operate properly when the setting is changed.
Note 2: When PZ-41SLB-E is used, the settings will be disabled for SW2-6, SW 5-1, SW5-4, SW5-5, and
SW5-7, and SW5-8.
( Operation after a recovery from a power failure will be fixed at power failure automatic recovery, and
functions other than this will be according to the setting of PZ-41SLB-E.)
Note 3: When the aforementioned switches (SW2 and SW5) are at the factory setting, LGH-F300 to F600
types will all be at the OFF setting, and LGH-F1200 type will all be set to OFF except for SW5-10.
When replacing the circuit board, set the new board to the same setting as that of the board prior to
replacement.
• Main/Sub selection switch
In systems of only one Lossnay unit, be sure to set it to "Main".
In systems with multiple Lossnay units, be sure that one unit is set to "Main", and that all the others are
set to "Sub".
When interlocked with an external device, be sure to connect the external device to the Lossnay that is
set to "Main".
When using PZ-60DR-E and mixing the LGH-F300 to F600 types together with the LGH-F1200 type in a
group, set the LGH-F300 to F600 types as "Main". ( When the LGH-F1200 type is set to "Main", Extra Low
operation is not possible. )
( 11 ) Function selection with PZ-60DR-E
When PZ-60DR-E is used, function selection can be made from the remote controller.
Functions can be switched from PZ-60DR-E even after the function selection switch has been set on the
Lossnay circuit board.
( Settings from PZ-60DR-E will have priority over function selection switch settings of the Lossnay circuit
board.)
When two remote controllers are used, "24HR VENTILATION", "LOSSNAY FUNCTION", and "INTERLOCK
SETTING" can be set only on the "Main" remote controller.
The "Main" and "Sub" remote controller will be determined automatically by communication when the main unit
power is turned on. The side on which "24HR VENTILATION", "LOSSNAY FUNCTION", and "INTERLOCK
SETTING" are displayed is the "Main" remote controller.
