9.7.7. Sensor Disconnection Detection Control<br />
• The sensor disconnection detection control activates when the following condition comply:<br />
Sensor Detection Threshold Duration (Sec.) Detection Condition<br />
Discharge Temperature < -4.5°C or 201.8°C 5 Other than compressor start control<br />
and compressor ON<br />
Outdoor Heat Exchanger < -50.5°C or 103.7°C 5 Regularly<br />
• During sensor disconnection, sensor error is displayed; all operations stops except outdoor fan remaining heat removal control.<br />
9.7.8. High-pressure Switch Disconnection Error Detection Control<br />
• High-pressure switch disconnection is detected when high-pressure switch input continuously open for 1 minutes while the compressor<br />
shutdown.<br />
• During this error, high-pressure switch error is displayed.<br />
9.7.9. Low-pressure Switch Disconnection Error Detection Control<br />
• Low-pressure switch disconnection is detected when low-pressure switch input continuously open for 1 minutes while compressor<br />
shutdown.<br />
• During this error, low-pressure switch error is displayed.<br />
9.8. Test Run<br />
• Test run is necessary after installation is completed.<br />
