TROUBLESHOOTING
Additional screens can be accessed by tabs on the main screen.
Additional screens include the following:
1. Cycleview (Figure 72): 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.
