DESCRIPTION
OF
APPLICATION
The communication module is designed for external control of an outdoor compressor unit called LG Electronics
in applications where the unit serves as the source of cold/heat in HVAC systems.
The superior HVAC control system defines the operational mode and power requirements.
The communication module is installed in a plastic box including the necessary power supply. The delivered
system includes refrigerant temperature sensors installed at the input and output of the heat exchanger in the
HVAC equipment.
The KM113.27UU module has 1 analogy input, 4 digital inputs, 2 digital outputs and 2 communication ports
(RS485) for controlling the compressor unit. The “MODBUS“ input/output is intended for communication with
the superior I&C system. The „POWER“ output is intended for direct synchronous reduction of the compressor
unit output according to the current power requirement.
3.1 Guaranteed compatibility of the communication module with compr. unit
