LG Monitoring View (LGMV) Diagnostic Software

LGMV software (PRCTSL1 and PRCTFE1) allows the service technician or commissioning agent to connect a computer USB port to the

Single Zone unit's main printed circuit board (PCB) using an accessory cable without the need for a separate interface device. The monitor-

ing screen for LGMV allows the user to view the following real time data on one screen:

• Actual inverter compressor speed

• Target inverter compressor speed

• Actual outdoor fan speed

• Target outdoor unit fan speed

• Actual superheat

• Target superheat

• Actual subcooler circuit superheat

• Target subcooler circuit superheat

• Main EEV position

• Subcooling EEV position

• Inverter compressor current transducer value

• Outdoor air temperature

• Actual high pressure/saturation temperature

• Actual low pressure/saturation temperature

• Suction temperature

• Inverter compressor discharge temperature

• Front outdoor coil pipe temperature

• Back outdoor coil pipe temperature

• Liquid line pipe temperature

• Subcooler inlet temperature

• Subcooler outlet temperature

• Average indoor unit (IDU) pipe temperature

• Inverter compressor operation indicator light

Additional screens can be accessed by tabs on the main screen.

Additional screens include the following:

1. Cycleview: Graphic of internal components including:

• Compressors showing actual speeds

• EEVs

• IDUs

• Temperature and pressure sensors

• Four-way reversing valve

2. Graph: Full screen graph of actual high and low pressures and high

and low pressure limits. A sliding bar enables user to go back in

time and view data.

3. Control FTN: Enables user to turn on IDUs in 1.8°F increments.

4. Useful Tab

• Unit Conversion: Converts metric values to imperial values.
