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.

previous requested condition. (When using PZ-60DR-E, PZ-41SLB-E, the start/stop condition from an external device is not
saved.)
