• The accurate sensing of cooling loads prevents frequent changes in capacity and ensures efficient, economical operation Inverter Module Protection
• Protects against differences in current, voltage and temperature
• Displays code on the indoor unit indicating a need for servicing
Outdoor Unit Microprocessor
• Electronic expansion valve control
• Automatic compressor timed-off protection (3 minutes)
• Temperature sensor
• LEDs on control display error codes and assist in troubleshooting
• 4-Way reversing valve control Electronic Expansion Valve
• Furnished on all models Compressor Overcurrent Protection
• Overcurrent protection can result due to any of the following:
• Ambient temperature is too high
• Locked rotor on the compressor
• Outdoor air is blocked or restricted Condenser High Temperature Protection
• Condenser high temperature can occur due to any of the following conditions:
• High outdoor ambient
• Outdoor fan blocked
• Outdoor coil blocked
• The outdoor coil thermistor continuously monitors the temperature and communicates with the microprocessor
• Depending on the temperature measured, the compressor will be allowed to increase the frequency if needed to meet the load or is forced to run at the current or reduced frequency
• If the temperature becomes excessively high the compressor will be de-energized.
Compressor Discharge Temperature Protection
• The compressor discharge line thermistor continuously monitors the temperature and communicates with the microprocessor
• Depending on the temperature measured, the compressor will be allowed to increase the frequency to meet the load or is forced to run at the current or reduced frequency
