Note 1
Note 1: Set LGH-15 to 100 types to the OFF setting, and LGH-150 and 200 types 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, type LGH-15 to 100 will
all be at the OFF setting, and type LGH-150 and 200 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
G In systems of only one Lossnay unit, be sure to set it to "Main".
G In systems with multiple Lossnay units, be sure that one unit is set to "Main", and that all the others are set to
"Sub".
G When interlocked with an external device, be sure to connect the external device to the Lossnay that is set to
"Main".
G When using PZ-60DR-E and mixing the LGH-15 to 100 types together with the LGH-150 and 200 types in a
group, set the LGH-15 to 100 types as "Main". (When the LGH-150 and 200 types are set to "Main", Extra
Low operation will not be possible.)
(11) Function selection with PZ-60DR-E
When using PZ-60DR-E, 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 SET-
TING" 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 SET-
TING" are displayed is the "Main" remote controller.
* For information about operation of PZ-60DR-E, refer to the Lossnay remote controller PZ-60DR-E Installation
Manual and the Operating Instructions.
