● Lossnay Remote Controller (PZ-41SLB-E
)
Use when operating from 1 to 15 Lossnay units together at the same time. When using M-NET transmission to operate from
centralised control, use the PZ-52SF-E.
It can start and stop the unit, change fan speed, switch the ventilation mode. It also includes indicators that show errors and
when filter maintenance is required. Refer to page 63.
● Lossnay M-NET Remote Controller (PZ-52SF-E
)
It can be used in combination with Mitsubishi Electric Air conditioner Network system (MELANS). Refer to page 69. Since
this remote controller is supplied the power from the M-NET transmission line, it cannot be linked with Mr. Slim and other
such systems that do not use M-NET.
Please refer to the technical documentation for the other systems: City Multi, Mr. Slim
and the central controller (MELANS).

3. Terminology
● Interlocked Lossnay
This is a Lossnay linked to City Multi, or Mr. Slim indoor units. This is a Lossnay that has been set to interlocked group setting to receive signals and operate via indoor unit’s remote controller → indoor unit → Lossnay.
● Non-interlocked Lossnay
This is a Lossnay that is not set to interlocked group setting with City Multi nor Mr. Slim indoor units. It operates using direct
operating signals from the Lossnay remote controller and/or centralised controller.
● Ventilation Mode
This mode controls the Lossnay damper and permits selection of heat recovery (Heat ex.), by-pass or auto modes.
● Delayed Operation
The Lossnay that has been set to interlocked group setting with the indoor unit will have its operation delayed for 30 minutes
after the operation of the indoor unit. When using PZ-41SLB-E, the time setting that can be set for delayed operation are 10,
20, 30, 40, 50, and 60 minutes.
● External Control Input
This is an input signal for operating the Lossnay that has been sent from an external device. It is compatible with 12V-24V
DC or uncharged a-contact signal.
● Operation Mode
This mode is used for selecting enabling/disabling of the on/off control signal from an external device and for setting interlocked operation of the external device and the Lossnay.
Please Refer to page 22 for details.
ON/OFF interlock: Enables both “ON → OFF” and “OFF → ON” external signals.
ON interlock: Enables “OFF → ON” external signal. Disables “ON → OFF” external signal.
OFF interlock: Enables “ON → OFF” external signal. Disables “OFF → ON” external signal.
External priority: Same as on/off interlock but the OFF signal from the remote controller is ignored when the
external control signal is on.
● Setting Pulse Input
When the control signal from the external device outputs a pulse such as the one shown below, pulse input setting is performed by the Lossnay. (Optional setting DIP switch 2-2 ON
)
200 ms or more
● Operation in Cold Areas
When the outdoor air is less than -10°C, continuous operation of the fan for drawing in supply air is cancelled, and intermittent operation is started.
● RA (Return Air
)
This is the abbreviation for return air, which is the air drawn in from indoor.
● OA (Outdoor Air
)
This is the abbreviation for outdoor air, which is the air drawn in from outdoor.

Be sure to make the Main/Sub setting when operating multiple Lossnay units.
When operating multiple Lossnay units, set the first one to “Main,” set the second and following to “Sub.”
Be sure the power is off when making the settings.
Change the Main/Sub switch (SW1) on the control board to “Sub” for the second and following Lossnay units.
Operation Method
Up to 15 Lossnay units (up to seven units when using LGH-150/200RX3-E) can be operated when running at the same time.
(Individual control is not possible)
Note:
● In the case of LGH-150/200RX3-E, there are two circuit boards installed in each unit. Therefore, count each unit as two units
in calculations when controlling multiple units. For example, 5 LGH-150RX
3-E units would count as 10 units. (For
150/200RX3-E type only, a maximum of seven units is possible.)

5.2 Delayed Interlocked Operation
(PZ-41SLB-E, M-NET)
(1) It is possible to delay operation of the Lossnay with respect to the operation of the external device. (Energy saving effect.)
(2) The times that can be set for delayed operation are 10, 20, 30, 40, 50, and 60 minutes.
(3) Delayed operation does not occur if the Lossnay operation was cancelled within the last 2 hours.
(If turned off for a short time, for example during a lunch break, if the direction to restart operation is given within 2 hours, the
Lossnay will restart immediately.)
(4) If an operation button is pressed on the remote controller while the delay timer is operating, the delayed operation is can-
celled and normal operation begins.
Setting Method
When PZ-41SLB-E is used . . . . . . Set with the remote controller. (Refer to page 67)
When PZ-41SLB-E is Not used . . . Set with the dip switch but fixed only for 30 minutes. (Refer to page 60)

5.4 Multiple Lossnay Units in Interlocked Operation 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 second and following
Lossnay units to “Sub,” and connect 5 and 6 of the Lossnay remote controller’s (PZ-41SLB-E) transmission cable terminal
(TM2) to the corresponding point on the next unit.
(
One Point Advice
)
Register the first Lossnay unit and the indoor unit to be interlocked.
It is not necessary to set the address or direct control for the second or following Lossnay units.
Malfunctions of the Lossnay units after the second unit will not appear on the remote controller.
[
Example: System 2
]
Use the Lossnay remote controller to set the air conditioners and Lossnay units to separate groups. Both interlocked operation
of an 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.
(
One Point Advice
)
Do not register the indoor unit and Lossnay unit to be interlocked. In addition, ventilation switch on the MA remote controller will
be invalid, and the Lossnays’ error indicator will appear only on the Lossnay remote controller.
