● 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.

6. Precautions When Designing Systems of M-NET
6.1
Power Supply of the M-NET Transmission Cable
On an M-NET system, the remote controller or central controller operate on power received from the transmission cable. Accordingly, there is need to provide power to the transmission cable.
There are two systems for supplying power. The central system is supplied by a power supply unit. The indoor unit system is
supplied by a outdoor unit. The Lossnay and the Lossnay remote controller can be connected to either system.
6.2 Restrictions When the Lossnay Units are Con-
nected to the Central Controller M-NET Transmission Cable.
Due to the limited capacity of the power supply unit, the number of Lossnay remote controllers is restricted when the Lossnay MNET remote controllers and Lossnay units are connected to the central controller transmission cable.
This does not apply to Lossnay units that do not receive power from the central controller transmission cable.

• In the case that a greater number of Lossnay remote controllers than that shown above is connected due to the use of a
power supply unit (PAC-SC34KUA), a transmission booster (PAC-SF46EPA) becomes necessary.
• Transmission Booster (PAC-SF46EPA) can be used without a power supply unit (PAC-SC34KUA) if TB2 (OUTDOOR UNIT
SIDE) is opened, and the M-NET transmission cable is connected to TB3 (ADDITIONAL INDOOR UNIT SIDE).

6.4 Power Supply to the Indoor Unit Transmission
Cable.
In principle, the number of indoor units ME remote controllers and Lossnay M-NET remote controllers that can be connected to
one outdoor unit will depend on the type of outdoor unit. The following are the general guidelines when connecting multiple
indoor units and Lossnay units to an outdoor unit.

7. Cable Installation of the M-NET
7.1 Precautions When Installing Wiring.
1. When routing transmission cable outside of the unit, position it 5 cm or more away
cable for the power supply so that it will not pick up electrical noise. (Never use multicore cable or place the transmission cable in the same conduit as the power supply
cable.
)
2. Never connect the power cable to the terminal block for the transmission cable. This
erroneous connection will burn out the circuit board.
3. Always use 2-core cable for the transmission cable. Routing this transmission cable
with the transmission cable from another system on the same multi-core cable will
result in erroneous sending and receiving of signals which will cause misoperation.

Please:
● Always install the ground cable for the transmission cables in the following way. Route the central control system through the
power supply unit. Route the indoor unit system through the ground terminal on the outdoor unit.
● If the cable length (o) for the remote controller exceeds 10 m, use 0.75 mm
2
, change the section exceeding 10 m to the cable
having a cross-sectional area of 1.25 mm
2
to 2.0 mm2. Add the exceeding section within the “maximum power supply cable
length” restriction of 200 m and the “maximum distance between ends” restriction of 500 m.
● If the cable exceeds the maximum cable length and overall extended length, voltage will drop and cause malfunctioning.

Precautions When Performing Interlock Settings
(
when interlocked with City Multi indoor unit
)
8.2
Precautions When Performing Group Settings
(
when not interlocked with City Multi indoor unit
)
Precautions
1
The maximum number of Lossnay units in one group is 16. (Refer to page 15.
)
2
When two remote controllers are used within the same group, set one remote controller as the master (address
101 to 150)and the other as the slave (address 151 to 200). (Refer to page 14.
)
3
Group settings:
1
Perform group settings at the centralised controller MJ-103MTRA when being used. If 2 or more centralised conntrollers are being used in combination, perform the group settings at the host one. (Refer to page 76.
)
2 If a centralised controller is not being used, use the Lossnay remote controller to perform the settings. (Refer
to page 72.
)
4
Do not set air conditioners and Lossnay units in the same group. If these units are set to the same group, the
indoor unit or Lossnay will not operate.
5
Turn on the power source for the Lossnay when performing group settings.
6
If the group settings are performed by MELANS, be sure to also set the address for the Lossnay remote controllers to the
group setting. If the remote controller address is not registered, “H0” remains displayed and the system does not start up.
7
No more than three Lossnay remote controllers can be set to the same group in a system using a central controller.
Precautions
1
The maximum number of indoor units that can be interlocked is 16. (Refer to page 17.
)
2
1 Lossnay can be interlocked with an indoor unit. (Refer to page 17.
)
3
Interlock settings:
1
When a centralised controller (MJ-103 MTRA)is being used: if 2 or more centralised controllers are being
used in combination, perform the group settings at the host one. (Refer to page 76.)
2 When MA or ME remote controllers are being used except above 1: Use the MA or ME remote controller for
the interlock settings. (Inerlock settings cannot be performed with the MJ-180A.
)
(
If 1 or 2 do not apply, interlock settings cannot be made.
)
4
Do not register the Lossnay units in a group to be interlocked.
Lossnay units that have been set to interlocked operation within the same group will not operate.
5
When performing the settings using a MA or ME remote controller, always set for interlocked operation to the
smallest address indoor unit in a group. If the setting is not made in this manner, the message “This function is
not available” will appear when operating the ventilation button and interlocking with the Lossnay unit will not be
possible.
6
Turn on the power source for the Lossnay when performing interlock settings.
36
9. Automatic Ventilation Switching
9.1 Effect of Automatic Ventilation Mode
The automatic damper mode automatically provides the correct ventilation for the conditions in the room. It eliminates the need
for troublesome switch operations when setting the Lossnay ventilator to “By-pass” ventilation. The following shows the effect
“By-pass” ventilation will have under various conditions.
1. Reduces cooling load
If the air outside is cooler than the air inside the building during the cooling season (such as early morning or at night), “Bypass” ventilation will draw in the cooler outside air and reduce the cooling load on the system.
2. Cooling using outdoor air
During cooler seasons (such as between spring and summer or between summer and fall), if the people in a room cause the
temperature of the room to rise, “By-pass” ventilation draw in the cool outside air and use it as is to cool the room.
3. Night purge
“By-pass” ventilation can be used to release hot air from inside the building that has accumulated in buildings a business district during the hot summer season.
4. Office equipment room cooling
During cold season, outdoor air can be drawn in and used as is to cool rooms where the temperature has risen due to the
use of office equipment.
(Only when interlocked with City Multi and Mr. Slim indoor unit)
9.2 Switching between Heat Recovery and Bypass in the Automatic Ventilation Mode
Control of the automatic ventilation mode is performed according to the table below and automatic algorithm temperature maps.
Note that operation is fixed at heat recovery when the fan is stopped or when there is an abnormality with the thermistor.

Note:
● There is a maximum delay of 30 seconds during damper switching.
● Even if “By-pass” is selected by the Lossnay remote controller, Lossnay ventilation will be performed if the outdoor tempera-
ture is 8°C or less. This is to prevent condensation.
● When multiple City Multi indoor units are connected in a group, the average set temperature for each indoor unit will be the
target temperature. The set temperature is the target temperature for the Mr. Slim indoor unit.
● In the case of (b)when the indoor unit is stopped for the winter, cooling with outdoor air is performed because equipment in
the room may cause a rise in indoor temperature.

Precautions when diagnosing malfunctions
● When removing a transistor or printed circuit board, make sure the breaker is thrown.
● When removing the circuit board, always hold it at both ends and remove carefully so as not to apply force to the surface
mounted parts.
● When removing the circuit board, be careful of the metal edges on the board.
● When removing or inserting the connectors for the circuit board, hold the entire housing section. Never pull on the lead wires.
● When servicing, be sure to recreate the malfunction 2 to 3 times before starting repairs.
● If a malfunction of the printed circuit board is suspected, check for disconnected wires in the print pattern, burnt parts or dis-

Installing the Lossnay M-NET Remote Controller
14.2.1 Mount the switch box.
1. Install the switch box (purchased separately)as explained below.
Note:
● Be sure to install the switch box with the clearance shown in the illustration at
the left. (Check the space between the unit and any projections, such as a
stud.)
● Leave a space of 120 mm or more below the Lossnay M-NET remote controller
so that a screwdriver can be used.
2. Purchase the thin copper wiring conduit, lock nuts and bushings separately.
1. Pull out approximately 80 mm of cable from the wall and remove the insulation
at the end.
2. Use putty to seal the cable hole in order to prevent insects from damaging the
wiring and to prevent condensation on the Lossnay M-NET remote controller
circuit board. If this hole is not sealed well, the Lossnay M-NET remote controller circuit board may be damaged.
3. Connect the cable to the terminal board at the bottom rear of the Lossnay M-
NET remote controller unit.
● The cable does not have polarity.
● When connecting stranded cable, hold down the tab on the terminal board
while inserting the cable.
● The cable connects to the main terminal board when it is inserted into the bot-
tom terminal.
● When disconnecting the cable, hold down the tab while pulling out the cable.
● After inserting the cable, slightly tug on it to check that it does not easily dis-
connect. If the cable is not securely connected, a short-circuit or malfunction
may occur.
4. Remove the Lossnay M-NET remote controller cover using a standard screw-
driver. Attach the Lossnay M-NET remote controller unit to the switch box
using the two enclosed cross-recessed pan head screws. Use a standard
screwdriver with a blade that is 4 mm or wider to remove the cover.
CAUTION:
● Forcing off the cover using a screwdriver that is less than 4 mm wide may
result in damage to the equipment or injuries.
