2. Product Outline
2.1 Outline and features
The LM ADAPTER is a communication interface to connect the Mitsubishi Electric made products for M-NET
use with the LONWORKS network. Only one LM ADAPTER can control and monitor indoor units up to 50
sets.
Since the LONWORKS network is an open protocol, connection with the Building management system
(BMS) and other products usable with LONWORKS can be performed easily thus allowing construction of
various systems including "Schedule operation," "Interlocked operation" and "Energy saving control".
<Features>
- Maximum 50 sets indoor units connectable with one LM ADAPTER
- Operation/monitoring with local remote controllers
- Standard Network Variables Type (SNVT) and enriched function (network variables)
- Various Configuration Properties (CP) essential for network construction

4.3 Selecting the system control parts
Using the system controller (SC) together other than LM ADAPTER allows connecting operation. Some
rules to be observed for this purpose are introduced below.
4.3.1 Master controller and slave controller
When LM ADAPTER is used together with other system controller inside a system under own control, it is
essential to set a slave SC(requiring a DIP-SW change). In this case, set it so that the control range of LM
ADAPTER is included within the control range of the system controller (air conditioner) which is to be the
master SC.

(1) In the case when the control range of the LM ADAPTER is covering that of plural system controllers, make
sure to install the Master system controller that covers the LM ADAPTER control range.
(2) In the case when the LM ADAPTER control range is covering the control range of the system controller
partially, install the system controller so that it covers the entire control range of LM ADAPTER.

4.3.2 Local remote controller
The local remote controller includes ME remote controller (PAR-F27MEA, etc.) to be connected to the
M-NET indoor-outdoor transmission line of air conditioners and MA remote controller (PAR-20MAA, etc.) to be
connected to each indoor unit. Each remote controller provides a different function usable by LM ADAPTER
and a different system construction method.

(2) Caution on a system without using remote controller
The following problems will be incurred when the operation/monitoring is done only from the BMS
(centralized monitoring system) without using the local remote controller. Therefore, please be sure to install a
local remote controller or system controller without fail.
①Test run can not be applied to air conditioners until the BMS has started up.
②Air conditioners can not be operated or monitored when trouble is generated on the BMS and
LM ADAPTER.
③The detail of the trouble i.e. the stopping of indoor units can not be clarified.
④The operation/setting of the items other than that controlled by the BMS cannot be performed.
⑤Interlocked setting of LOSSNAY and air conditioners can not be performed.

4.3.3 External contact input/output
The external contact input/output function is not provided to LM ADAPTER.
4.3.4 Power supply to M-NET transmission line
The M-NET centralized system controller line should be powered. For the system using other system
controller or that with LOSSNAY only, the power supply unit for transmission line is required. In accordance
with the system configuration, the setting of LM ADAPTER and outdoor units should partially be changed.
Please conduct the setting operation by referring to the "Installation Manual" of LM ADAPTER. For the power
supply capacity of the power supply unit and the selection of the unit, please refer to the manuals (like DATA
BOOK) of each air conditioner.

4.5 Restrictions on system configuration
The restrictions in constructing the system by LM ADAPTER are outlined here.
4.5.1 Restrictions by system configuration
(1) Group control
In the case when the group setting of indoor units are carried out by the local remote controller or system
controller, the operation from the BMS is performed as follows.

When using “Forced Thermostat OFF” is
required to request into indoor units individual

4.5.2 Restrictions by control items
(1) Operation prohibit
①When using together the system controller that can set to prohibit the local remote controller operation,
make the controller for setting of operation prohibit one unit, either LM ADAPTER (BMS) or the system
controller.
②Operation prohibit can not be applied to other system controllers by LM ADAPTER (from BMS)
③Although air conditioners can not be operated by the local remote controller of which operation is being prohibited,
they can be operated by LM ADAPTER (BMS) or other system controllers.
1At the unit of lowest address in the same group

17
(2) Emergency stop
The emergency stopping of LM ADAPTER stops all air conditioners together, however it does not set the
operation prohibit of the local remote controller allowing the operation from other system controller or local
remote controller. To prohibit operation from the local remote controller, therefore, set it by entering
[Request Collective Local Prohibit] (collective).
*Operating to run during emergency stopping only results in immediate stopping.
(3) Operation mode
In the case of cooling/heating selectable models of CITY MULTI, the operation mode will be determined by
the principle of the "Priority for former pressing." Under the circumstance, a same command should be
issued to all indoor units within a same refrigerant system to change the operation mode.
