5.4 Multiple Lossnay Units Interlocked with One
Indoor Unit (M-NET only)
[ Example: System 1 ]
Set the Main/Sub switch of the Lossnay connected to the M-NET transmission cable to "Main," set the other Lossnay units to
"Sub," and connect 1 and 2 of the Lossnay remote controller (PZ-60DR-E or PZ-41SLB-E) transmission cable terminal
(TM4) to the corresponding terminal on the next unit.
Note:
Make the setting of the first Lossnay unit and the indoor unit to be interlocked.
It is not necessary to set the address or control for other Lossnay units, directly.
Malfunctions of the Lossnay units for sub units will not appear on the remote controller.
[ Example: System 2 ]
When you want to also monitor and manage the Sub set Lossnay malfunctions via a centralized controller, wire all of the TM4
of Lossnays, set the main/sub switch of the Lossnay of the smallest address to "Main", and set other Lossnays at "Sub."
From the centralized controller, set indoor unit and Lossnays group registration, respectively, and set the interlock with an
indoor unit and a Lossnay of the smallest address in a group.
Centralized controller
[ Example: System 3 ]
Use the Lossnay remote controller to set the indoor units of air conditioner and Lossnay units to separate groups. Both inter-
locked operation of an indoor unit of air conditioner and Lossnay units can be performed independently by connecting the
remote display output for the indoor unit and the external control input for the Lossnay unit.
Note:
Do not make the setting of the indoor and Lossnay units to be interlocked, because the ventilation switch on the MA remote
controller will become invalid, and the error indicator for the Lossnay unit will appear only on the Lossnay remote controller.
