Dip Switch Settings For Use With Gen 4 Indoor Units - LG MULTI V 5 Engineering Manual

DIP SWITCH SETTINGS FOR USE WITH
GEN 4 INDOOR UNITS
Generation 4 Equipment
The latest versions of LG's indoor units are designated Generation 4 (Gen 4). For Gen 4 indoor units to operate with Gen 4 indoor unit fea-
tures, the air conditioning system must meet the following requirements:
• All indoor units, heat recovery units, and air / water source units
must be Gen 4 or higher.
• All air / water source units must have Gen 4 or higher software
installed.
• Air / water source units DIP switch 3 must be set to ON
(factory default setting is OFF).
• All controllers must support Gen 4 indoor unit features.
The figure at right shows the outdoor unit DIP switch. The "System
Component Combinations and Operation Status" table lists how
combining different components will affect system operation. The
"Serial Numbers or Air / Water Source Units with Gen 4 or Higher
Software" table lists the serial numbers of air and water source
units that have Gen 4 or higher software. All air and water source
units, indoor units, heat recovery units, and controllers in a system
must be Gen 4 compatible or the system will not operate with Gen 4
indoor unit features.

software, Multi V Mini, Multi V Water Mini, or Multi V Space II.
**Gen 4 Indoor Units model numbers end in "4"; Gen 2 Indoor Units model numbers end in "2" or an "A", including Hydro Kit.
***DIP Switch No. 3 on Gen 2 air / water source units is not related to Gen 4 features as it is with Gen 4 air / water source units.
****0A Model Heat Recovery units are not for use with Multi V 5, Multi V IV, Multi V Water IV, or Multi V III heat recovery systems.
