(2) System checklist when using the M-NET (Table 1-2-2)
Symptom
No.
1
Does not interlock with
City Multi. (The Lossnay
cannot be operated by
the ventilation switch on
the ME remote controller,
MA remote controller, or
MELANS.)
2
Cannot operate using the
MELANS or Lossnay
remote controller.
3
A unit should operate
independently by
MELANS or the Lossnay
remote controller, but it
interlocks with another
City Multi unit.
4
Cannot perform group
settings for the Lossnay
using MELANS, ME
remote controller, or MA
remote controller. (The
remote controller shows
"88" at the time of regis-
tration.)
5
When power is supplied
to the system, the Loss-
nay remote controller
continues to display "HO"
and does not start.
(Group registration infor-
mation disappears.)
6
When power is supplied
to the system, the
remote control display
goes blank and the sys-
tem does not start.
Cause
« The Lossnay is not set for interlocked opera-
tion, or is set for interlocked operation at the
wrong address.
« The length of the M-NET transmission cable
wiring from the outdoor unit or the system's
overall wiring length is longer than specifica-
tions. (Longer than 200 m from the outdoor
unit, longer than 500 m between ends.)
« PZ-41LSB-E is connected to the Lossnay local
remote controller.
« The address that has been set for the group in
MELANS and the address for the Lossnay are
different.
« The length of the M-NET transmission cable
wiring from the power supply unit or the sys-
tem's overall wiring length is longer than speci-
fications. (Longer than 200 m from the power
supply unit, longer than 500 m between ends.)
« PZ-41LSB-E is connected to the Lossnay local
remote controller.
« It has been set for interlocked operation with
the City Multi unit.
« Power is not supplied to the Lossnay, or power
outside specifications is connected.
« The M-NET transmission cable is connected to
TM2 5,6.
« The transmission cable is not properly con-
nected to the MELANS or the City Multi.
« The length of the transmission cable wiring is longer than
specifications (longer than maximum 200 m from the
power supply unit, longer than 500 m between ends.)
« The Group setting was made on a Lossnay
remote controller in a system connected to a
centralised controller MELANS.
« The length of the transmission cable wiring is
longer than specifications (longer than maxi-
mum 200 m from the power supply unit, longer
than 500 m between ends.)
« Over the number of units that can be controlled
with the Lossnay remote controller.
« The length of the transmission cable wiring is
longer than specifications (longer than maxi-
mum 200 m from the power supply unit, longer
than 500 m between ends.)
Corrective action
« Check the Lossnay address, and
set for an address correspond-
ing to interlocked operation.
(refer to "15. Appendix")
« Check the length of the trans-
mission cable wiring.
« Change to the PZ-52SF-E remote
controller (PZ-41SLB-E can not
be used with the M-NET).
« Check the registered address in
MELANS. (refer to "15. Appendix")
« Check the length of the trans-
mission cable wiring.
« Change to the PZ-52SF-E remote
controller (PZ-41SLB-E can not be
used with a M-NET system).
« Cancel the interlocked operation
setting. (refer to "15. Appendix")
« Check the power for the Lossnay
and perform the registration again.
(refer to "15. Appendix")
« Connect the transmission cable
to TB5 A, B. (refer to page 165)
« Check the transmission cable
connection. (refer to page 165)
« Check the length of the trans-
mission cable wiring.
« In a system connected to MELANS,
make the group setting with the
MELANS (Do not make the group set-
ting with the Lossnay remote controller).
(refer to "15. Appendix" or page 179)
« Check the length of the trans-
mission cable wiring.
« Check remote control unit number
limitations when using a power
supply unit (refer to page 134).
« Check the length of the trans-
mission cable wiring.
