Mitsubishi Electric Lossnay LGH-RX5-E Series User manual

Lossnay
Remote Controller

C-3
1. Summary
Technical manual detailing the control and operation of commercial-type Lossnay units (LGH-RX5-E Series).
Possible System Configurations
(1) When using only the Lossnay remote controller.
(2)Linking Lossnay and City Multi units.
(3)Linking Mr. Slim.
(4)Lossnay central control systems.
(5)Linking with external equipment (BMS).
2. Applicable Models
●Lossnay (LGH-RX type)
These models have temperature sensors at return stale indoor air (RA) and outside air intake (OA) sides and can automati-
cally switch to ventilation (Lossnay/By-pass) mode.
●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 cen-
tral 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 operat-
ing 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 (CO2sensor 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: 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 control 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 per-
formed 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 oper-
ation 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.

using a transmission cable (PVC insulated PVC jacketed
and either between 0.65 and 1.2, or between 0.3 mm2and
1.25 mm2in cross section).
(2) Change the setting on the main/sub switch (SW1) on the
second and subsequent Lossnay units to “Sub”.
CAUTION:
Don’t tighten screws of terminal block with a torque larger than
0.5 Nm. It could damage the PCB.
Note:
●Up to four 0.3 mm2stranded wires or 0.65 PVC wires can
be connected to one input terminal.
●For other types of wire, up to two can be connected.
●The operation signal and pulse signal can be connected to
the external device of the main Lossnay only.
●Connect the power to each respective Lossnay unit.
●When the LGH-150RX5and LGH-200RX5types are connect-
ed, they operate at low fan speed even if extra low fan speed
is selected.

Setting Method
(1) Make the Group setting for the indoor unit.
(2) Make the Group setting for the Lossnay unit.
(3) Set the indoor unit and Lossnay unit for interlocked operation.
When using the centralized controller, make both the Group setting and operation setting with centralized controller.
Characteristics
(1) When the indoor unit is set for interlocked operation in one group:
Interlocked Lossnay operation is possible with indoor unit remote controller. In this case, operation can switch between
High/Low/Off. It is possible to switch Lossnay operation only between High/Low/Off with the indoor unit remote controller.
It is possible to controll the Lossnay unit from Lossnay remote controller PZ-60DR-E. More additional function such as Extra
Low fan speed is available.
(2) When two or more indoor units in different groups are set for interlocked operation, the Lossnay will operate if at least one
group operates. The Lossnay will stop operation if all groups stop operation.
It is possible to switch the Lossnay only between High/Low when other groups are operating with indoor unit remote con-
troller.
It is possible to controll the Lossnay unit from Lossnay remote controller PZ-60DR-E. More additional function such as Extra
Low fan speed is available.
Note:
●If the display on the MA, ME or other indoor unit remote controllers is cancelled, the indoor unit remote controller will not
show the ventilation display even if Lossnay is operating via the Lossnay remote controller PZ-60DR-E.
Note:
Power supply limitation of transmission cable for indoor unit.
●Indoor units + ME remote controllers (compact remote controllers) is less than or equal to 40 units.
●Indoor units are less than or equal to 20 units.
(MA remote controllers and Lossnay units are not included in the 20 units, listed above.)

C-20
System Examples: 2
A sophisticated system including City Multi can also be configured.
Note:
●Hard wire connection from PZ-60DR-E is required independent from M-NET line. If change the Group setting in the future, it
is required to change the wiring of PZ-60DR-E.
●Do not use Lossnay remote controller PZ-41SLB-E.
