● 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.

Combined Line Method

Connect the transmission cable from the first Lossnay to the second, the second to the third, and so on up to a maximum of 15 units.

(1) Up to four wires can be connected to one signal terminal when a transmission cable is ø0.65 or strand wire 0.3 mm

, or up

to 2 wires in other cases.

(2) The signal is non-polar, so it is not necessary to align polarity.

Lossnay Main/Sub Setting

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.)

: Compatible × : Incompatible

System Examples: 1

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 in interlocked operation. When using the centralised controller, make both the Group setting and operation setting for the previously mentioned units. Though the MJ-180A cannot set interlocked settings, it should set at MA/ME remote controllers.

Characteristics

(1) When the indoor unit is set for interlocked operation in 1 group:

Interlocked operation with the indoor unit from the air conditioner remote controller is possible and can switch between High/Low/Off. From the air conditioner remote controller it is possible to switch the Lossnay only between High/Low/Off. From the Lossnay remote controller it is possible to switch the Lossnay between High/Low/Off.

(2) When the 2 or more indoor units with different group are set for interlocked operation, the Lossnay will operate if at least 1

group operates. The Lossnay will stop operation if all groups stop operation. From an air conditioner remote controller it is possible to switch the Lossnay only between High/Low when other groups are operating. From the Lossnay remote controller it is possible to switch the Lossnay between High/Low/Off.

Note:

● If the display on the MA remote controller/ME remote controller, or other air conditioner remote controller, is cancelled, the air

conditioner remote controller will not show the ventilation display even if you operate the Lossnay from the Lossnay M-NET remote controller.

Note:

Transmission cable power control for indoor units Be sure usage is within the following boundaries.

● Indoor units + ME remote controllers (compact remote controllers) + Lossnay M-NET remote controllers is less than or equal

to 40 units.

● Indoor units are less than or equal to 20 units.

(The numbers of MA remote controllers and Lossnay units are not included in the above number of units.)

System Examples: 2

A mixed system including the City Multi can also be configured.

Note:

● Do not use Lossnay remote controller PZ-41SLB-E in case of a system using M-NET transmission cable.
