cannot be operated by
the ventilation button on
the ME remote control-

different City Multi units.
Cause
 The interlock mode is set to " ON Interlocked "
or " OFF Interlocked " with the remote controller
( PZ-60DR-E ) .
 The interlock mode is set to " 2 " ( ON Interlocked )
or " 3 " ( OFF Interlocked ) with PZ-41SLB-E.
 When PZ-60DR-E and PZ-41SLB-E are not
used, the delay setting switch ( SW5-1 ) on the
Lossnay circuit board is set to ON. ( During the
delay operation, LED1 ( green ) on the Lossnay
circuit board will be lit. )
 When PZ-60DR-E and PZ-41SLB-E are not
used, the interlock mode setting switches ( SW5-
7, SW5-8 ) on the Lossnay circuit board are set
to " ON Interlocked " or " OFF Interlocked " .
 When multiple Lossnay units are used, the
external control input signal is connected to a

 Check the Lossnay address, and
set for an address corresponding
to interlock operation.
 Check the length of the transmis-
sion cable wiring.
( See the technical manual for
details about the regulations. )
 Change the remote controller to
PZ-60DR-E or PZ-52SF-E. (PZ-
41SLB-E cannot be used with the
M-NET.)
 Check the registered address in
MELANS.
 Check the length of the transmis-
sion cable wiring.
( See the technical manual for
details about the regulations. )
 Change the remote controller to
PZ-60DR-E or PZ-52SF-E. (PZ-
41SLB-E cannot be used with the
