● Lossnay Remote Controller (PZ-60DR-E)
It is possible to control all of the function of LGH-RX5-E, such as, Extra-Low-fan speed, weekly timer.
Use when operating from 1 to 15 Lossnay units together at the same time.
PZ-60DR-E is not M-NET control, however, LGH-RX5-E can be use with PZ-60DR-E in the M-NET system. (Refer to page
C-78).
● 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
a centralized remote controller, use the PZ-60DR-E OR PZ-52SF-E.
It can start and stop the unit, change fan speed, and switch the ventilation mode. It also includes indicators that show errors
and when filter maintenance is required Function is limited in case of LGH-RX5-E (Refer to page C-91).
● Lossnay M-NET Remote Controller (PZ-52SF-E)
Use with Mitsubishi Electric Air conditioner Network system (MELANS) (Refer to page C-92). Because the remote controller
is power-supplied using the M-NET transmission line, it cannot be linked with Mr. Slim and other such systems that do not
use M-NET. It can start and stop the unit, change fan speed, and switch the ventilation mode. It also includes indicators that
show errors and when filter maintenance is required Function is limited in case of LGH-RX5-E (Refer to page C-92).
Please refer to the technical documentation for City Multi, Mr. Slim systems and the central controller (MELANS).

3. Terminology
● Interlocked Lossnay
A Lossnay linked to City Multi or Mr. Slim indoor units that has been set to interlocked group setting to receive signals and
operate via indoor unit’s remote controller. (Remote controller to indoor unit to Lossnay.)
● Non interlocked Lossnay
A Lossnay that is not set to interlocked group setting with City Multi or Mr. Slim indoor units. It operates using direct operating signals from the Lossnay remote controller and/or centralized remote controller.
● Ventilation Mode
Controls the Lossnay damper and permits selection of heat recovery (heat exchange), By-pass or auto modes.
● Timer control. (PZ-60DR-E)
PZ-60DR-E has weekly timer and simple timer.
• weekly timer : The operation pattern for each day of the week and the air-volume by time zone can be set (up to eight
zones per day).
• simple timer : Three setting is available , start-timer only, stop time only or start & stop.
● Delayed Operation
A 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, delayed operation can be set for 10, 20, 30, 40, 50 and 60
minutes.
● External Control Input
• An input signal from an external device used to operate Lossnay. It is compatible with 12V-24V DC or uncharged a-contact
signal.
• Switching High Low or Extra-Low fan speed is available by external input (CO2 sensor or other equipment is connected).
• Switching By-pass is available by external input.
● Operation Mode
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 Lossnay.
Please Refer to page C-23 for details.
(
ON/OFF interlock:
ON interlock:
OFF interlock:
External control priority:
Enables both “ON → OFF” and “OFF → ON” external signals.
Enables “OFF → ON” external signal. Disables “ON → OFF” external signal.
Enables “ON → OFF” external signal. Disables “OFF → ON” external signal.
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 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 fan operation for drawing in supply air is cancelled and intermittent operation is started.
● RA (Return Air)
Abbreviation for return air, which is the air drawn in from inside.
● OA (Outdoor Air)
Abbreviation for outdoor air, which is the air drawn in from outside.

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.

6. Precautions When Designing M-NET
Systems
6.1
M-NET Transmission Cable Power Supply
On an M-NET system, the remote controller or central controller operate on power from the transmission cable. Accordingly,
there is need to provide power to the transmission cable.
Two systems are available for supplying power: the central system is supplied by a power supply unit; the indoor unit system is
supplied by an outdoor unit. The Lossnay unit and the Lossnay remote controller can be connected to either system.

Restrictions When the Lossnay Units are Connected to the Central Controller M-NET Transmission Cable
The power supply unit has limited capacity; therefore, the number of Lossnay remote controllers is restricted when the Lossnay
M-NET remote controllers and Lossnay units are connected to the centralized controller transmission cable. The restriction does
not apply to Lossnay and G-50A units that do not receive power from the centralized controller transmission cable.

• If a larger number of Lossnay remote controllers than that shown above is connected due to the addition a power supply unit
(PAC-SC50KUA, PAC-SC51KUA), a transmission booster (PAC-SF46EPA) is necessary.
• Transmission Booster (PAC-SF46EPA) can be used without a power supply unit (PAC-SC50KUA, PAC-SC51KUA) if TB2
(outdoor unit side) is opened, and the M-NET transmission cable is connected to TB3 (additional indoor unit side).

The number of ME and Lossnay M-NET remote controllers that can be connected to one outdoor unit will depend on the type of
outdoor unit. See below for the general guidelines when connecting multiple indoor units of air conditioner and Lossnay units to
an outdoor unit.
Indoor units of air conditioner + Remote controllers (Simple remote controllers) + Lossnay M-NET remote controllers 32*2
*1 MA remote controllers and Lossnay units are not counted.

7. M-NET Cable Installation
7.1
Precautions When Installing Wiring
1. When routing the transmission cable outside of all units, 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 transmission cable terminal block; it will burn
out the circuit board.
3. Always use two-core cable for the transmission cable. Do not route this transmission
cable with the transmission cable from another system on the same multi-core cable;
it will result in signal error and cause the system not to operate properly.

Notes:
● Always install the ground cable for the transmission cables by routing the central control system through the power supply
unit, then routing the indoor unit system through the ground terminal on the outdoor unit.
● If the cable length (R) for the remote controller exceeds 10 m, use a cable with a 0.75 mm2 diameter, but change the section
exceeding 10 m to a cable with a diameter of 1.25 mm2 to 2.0 mm2. Cable length (R) exceeding 10m should be included in the “maximum power supply cable length” restriction of 200 m and the “maximum distance from ends to ends of units” restriction of 500 m.
● If the cable exceeds the maximum cable length and overall extended length, voltage will drop and cause the system to malfunction.

Precautions When Setting the Groups (when not
interlocked with City Multi indoor units)
Precautions
1
The maximum number of Lossnay units in one group is 16. (Refer to page C-16.)
2
When two remote controllers are used within the same group, set one remote controller as the main (address
101 to 150) and the other as the sub (address 151 to 200). (Refer to page C-15.)
3
Group settings:
1 Set the groups at the System Controller. If two or more System Controllers are used in combinations, perform them at the main one. (Refer to page C-93.)
2 If a System Controller is not being used, use the Lossnay remote controller to set the groups. (Refer to page
C-92.)
4
Do not set the indoor units of air conditioner and Lossnay units in the same group. If these units are set to the
same group, neither the indoor unit nor Lossnay will operate.
5
Turn on the power source for the Lossnay when setting the groups.
6
If MELANS is being used to set the groups, 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” is 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 System Controller.
8.3
Precautions When Performing Interlock Settings
(when interlocked with City Multi indoor units)
Precautions
1
The maximum number of indoor units of air conditioner that can be interlocked is 16. (Refer to page C-18.)
2
One Lossnay can be interlocked with an indoor unit of air conditioner. (Refer to page C-18.)
3
Interlock settings:
1 Perform interlock settings at the System Controller. If two or more System Controllers are used in combinations, perform them at the main one. (Refer to page C-93.)
2 When MA or ME remote controllers are being used except above 1, use the MA or ME remote controller for
the interlock settings.
(If 1 or 2 does not apply, interlock settings cannot be made.)
4
Do not register the Lossnay units to the other Lossnay group.
In this case, the Lossnay units aren’t interlocked to the other Lossnay group.
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.
C-39
9. Automatic Ventilation Switching
9.1
Effect of Automatic Ventilation Mode
The automatic damper mode provides the correct ventilation for the room conditions. 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 any accumulated hot air from inside the building 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 office
equipment use.
(Only when interlocked with City Multi and Mr. Slim indoor unit)
9.2
Ventilation mode control
Lossnay (heat exchange) ventilation or bypass (normal) ventilation is achieved by switching the air duct inside the
Lossnay unit with a damper.
1 Ventilation mode
There are 3 control modes.
● Lossnay ventilation (heat exchange ventilation) mode: Heat exchange ventilation is performed regularly via
the Lossnay core.
● Bypass ventilation (normal ventilation) mode
: Ventilation is performed regularly without going
through the Lossnay core.
● Automatic ventilation mode
: A temperature sensor built into the unit provides
automatic ventilation to a suitable ventilation mode.
In addition, energy saving ventilation is provided by
interlocking with a Mr. Slim or City Multi indoor unit.
2 Damper control for each system
The control indicated below can be performed according to the system that is paired
Caution
C-40
●Up to two of the Lossnay remote controllers PZ-60DR-E, PZ-41SLB-E, and PZ-52SF-E can
be used in the same group, but they cannot be used together with a different remote controller. When using two remote controllers, be sure to use the same model of remote controller.
●PZ-41SLB-E cannot be used in M-NET control. When controlling Lossnay in M-NET control,
use PZ-60DR-E or PZ-52SF-E.

■ To force High fan speed externally
When SW1 is "ON", fan speed of the Lossnay will be set to
"High"(Extra-High) regardless of the remote control setting.
Use this in such a way that it ventilates at Low or Extra-Low
fan speed normally, and when the external sensor detects
contamination of indoor air, it changes to High (Extra High)
fan speed operation.
■ To force Low fan speed externally
When SW1 is "ON", fan speed of the Lossnay will be set to
"Low" regardless of the remote control setting.
Use this in such a way that it ventilates at High fan speed
normally, and when the external sensor detect that the indoor
air contamination is low, it changes to Low fan speed operation.
■ To force Extra-Low fan speed externally
When SW1 is "ON", fan speed of the Lossnay will be set to
"Extra-Low" regardless of the remote control setting.
Use this in such a way that it ventilates at High fan speed
normally, and when the external sensor detects that the
indoor air contamination is low, it changes to Extra-Low fan
speed operation.
* For the LGH-150RX5 and LGH-200RX5 types, fan speed of
the Lossnay will be “Low”.
