DIP SWITCH SETTINGS FOR
GEN4 EQUIPMENT

Generation 4 Equipment

The latest versions of LG's indoor units and outdoor (air / water source) units are designated Generation 4 (Gen 4). For Gen 4 units to oper-
ate with Gen 4 features, the air conditioning system must meet the following requirements:
• All indoor units, heat recovery units, and air / water source units
must be Gen 4.
• All air / water source units must have Gen 4 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 features.
The figure at right shows the ODU DIP switch. The "System Com-
ponent Combinations and Operation Status" table lists how combin-
ing different components will affect system operation. The "Serial
Numbers or Air / Water Source Units with Gen 4 Software" table lists
the serial numbers of air and water source units that have Gen 4
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 features.

*Gen 4 Air / Water Source Units = Multi V IV or Multi V Water IV with Gen 4 software (see table below for Gen 4 serial numbers) or Multi V S.
Gen 2 Air / Water Source Units = Multi V II, Multi V III, Multi V IV without Gen. 4 software, Multi V Water II, Multi V Water IV without Gen. 4
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 IV, Multi V Water IV, or Multi V III heat recovery systems.
