1. For connection of a remote controller (PZ-41SLB-E)
If the Lossnay’s operation is linked with the operation of an external device such as an air conditioner, the method of use will differ, so carry out
the appropriate operation in accordance with the following table. Also, please see the installation and user’s manual for the remote controller
(PZ-41SLB-E).
2. For connection of a Lossnay remote
controller (PZ-52SF-E), Mitsubishi
Electric Air-Conditioner Network
System (MELANS) or City Multi.
This is to be incorporated and used in the Mitsubishi Electric Air-
Conditioner Network System.
This is interlocked with the City Multi and operated by it.
If the Lossnay remote controller (PZ-52SF-E) is used, the Lossnay
may be operated independently if connected to City Multi.
For details, refer to the operating manual of PZ-52SF-E.
Lossnay operation using the Lossnay remote controller (PZ-52SF-
E) should need the power supply unit. Refer to the system diagram
below.
Note
• If this is to be used with the Lossnay remote controller (PZ-
52SF-E), refer to the manuals for both the PZ-52SF-E instal-
lation and operating manual.
• Remote controller PZ-41SLB-E cannot be used with this sys-
