Energy Savings
Although VRF technology inherently results in an extremely efficient system, there are several ways in which controls can
help save even more energy:

Scheduling and occupancy detection – Conditions the space only when necessary.

Setpoint range limit – Prevents the setpoint from being set to extremes that can result in overcooling or overheating
of the space.

Remote controller lock – Prevents users from changing indoor unit operation.

Temperature limit – Allows indoor units to be shut off during unoccupied periods with an override feature to keep
interior temperatures from reaching extremes.

Time limit (unoccupied override) – Permits a unit to be turned on during unoccupied times and automatically shut
down after a specified amount of run time.
Convenience

Auto-changeover – Automatically switches the indoor unit into the correct mode to optimize space comfort.

Central control – Allows distributed control from one location.

Web access – Allows distributed control from a remote location.

Visual and e-mail alarm notification – Immediately indicates when a system is not operating at optimal conditions.
Multi V Controls
By utilizing advanced control strategies, LG’s HVAC and variable refrigerant flow (VRF) systems not only
save energy, but they also increase operational convenience and living standards. LG offers a variety of
control systems, including individual zone control, central control, and building management system
integration control options that scale easily to meet the requirements of jobs small to large.
User-friendly controllers featuring advanced functionality and easy-to-read liquid crystal displays (LCDs)
allow users to control and monitor their entire system at the touch of a button. Centralized controllers
provide building owners, facilities managers,
and maintenance personnel with highly
efficient control of LG VRF systems. This allows
convenient management of air conditioning
units and other facilities equipment, even in
multiple sites.
LG building controllers have reached a greater
level of integration in the world of standards,
protocols, and data distribution systems that
allow for interfacing with third-party building
management systems and also controls
sub-market segments such as lighting control,
security control, and access control. Overall,
LG controllers offer a very competitive price to
feature ratio.
