How to troubleshoot Hitachi Air Conditioner LCD H-link RCS transmission error?
If your Hitachi Air Conditioner shows 'LCD H-link RCS transmission error', inspect and repair the H-link communication wiring. The cause is no H-link communication for a continuous period of 1 minute between Indoor and LCD User control by connection wiring (breaking, wiring error, etc.)
How to reconfigure LCD settings on Hitachi YUTAKI S80?
If your Hitachi Air Conditioner displays 'Incorrect LCD setting', reconfigure the LCD settings. This indicates that the current LCD configuration does not allow proper operation.
How to fix Hitachi YUTAKI S80 transmission alarm?
If your Hitachi Air Conditioner displays a 'Transmission Alarm (Not outdoor unit detected)', it typically indicates a connection issue. Check the connectors for any looseness or breakage, as the cause may be a loose, disconnected, broken, or short-circuited connector.
What does Abnormality of Power Supply Phase mean on Hitachi Air Conditioner?
If your Hitachi Air Conditioner displays 'Abnormality of Power Supply Phase', check the power supply phase connections, as the cause is a reverse or open phase.
What causes excessively high discharge gas temperature at the top of compressor in Hitachi Air Conditioner?
If your Hitachi Air Conditioner shows 'Excessively high discharge gas temperature at the top of compressor', inspect refrigerant levels and expansion valves. This can be caused by insufficient refrigerant charge, refrigerant leakage, or an expansion valve that is closed or clogged.
What does Decrease in discharge gas superheat mean for Hitachi YUTAKI S80?
If your Hitachi Air Conditioner displays 'Decrease in discharge gas superheat', check refrigerant charge and inspect related components. Possible causes are excessive refrigerant charge, failure of thermistor, incorrect wiring, incorrect piping connection, or expansion valve locking at opened position (disconnected connector).
How to solve RF Communication failure on Hitachi YUTAKI S80 Air Conditioner?
If your Hitachi Air Conditioner shows 'RF Communication failure', check the RF communication setup. This issue occurs when there is no communication for 1 hour with one or two RF receivers which are bound to the RF-Bridge.
How to solve Incorrect capacity setting or combined capacity between outdoor and indoor units on Hitachi YUTAKI S80 Air Conditioner?
If your Hitachi Air Conditioner displays 'Incorrect capacity setting or combined capacity between outdoor and indoor units', ensure proper capacity settings for both units. This is caused by an incorrect Capacity Code Setting, or Excessive or Insufficient Indoor Unit Total Capacity Code.
What causes Activation of protection device (high pressure cut) on Hitachi YUTAKI S80?
If your Hitachi Air Conditioner displays 'Activation of protection device (high pressure cut)', inspect the entire system for the mentioned failures. This can be caused by activation of PSH, locked motor, abnormal operation in the power supply phase, failure of fan motor, drain discharge, PCB, relay, float switch activated, pipe clogging, excessive refrigerant, or inner gas mixing, or fan motor locking at cooling operation.
What to do if Hitachi YUTAKI S80 activates the protection device for the indoor fan motor?
If your Hitachi Air Conditioner displays 'Activation of the protection device for the indoor fan motor', inspect the indoor fan motor for operation, as the cause is a failure of fan motor.
