How to fix Incorrect PCB Setting in Hitachi Air Conditioner?
If your Hitachi Air Conditioner shows 'Incorrect PCB Setting', correct the DSW settings. This issue is caused by a wrong DSW setting in the case of Co041.
What causes RF communication failure in my Hitachi YUTAKI S80?
RF communication failure in your Hitachi Air Conditioner happens when there is no communication for 1 hour with one or two RF receivers which are bound to the RF-Bridge.
What causes Hitachi YUTAKI S80 Air Conditioner hydraulic alarm pressure?
If your Hitachi Air Conditioner displays 'Hydraulic alarm pressure', check the system for any leaks or blockages affecting water pressure. This alarm indicates that water pressure is not detected in the hydraulic cycle.
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.)
What causes abnormal decrease of discharge gas superheat degree in my Hitachi YUTAKI S80?
Abnormal decrease of discharge gas superheat degree in your Hitachi Air Conditioner can be caused by excessive refrigerant, expansion valve open-locked, or fan motor locked.
What causes failure of ambient temperature thermistor in my Hitachi YUTAKI S80?
Failure of the ambient temperature thermistor in your Hitachi Air Conditioner is caused if the ambient temperature thermistor is short-circuited or cut.
What causes water outlet C2 thermistor abnormally (THM WO2) in my Hitachi YUTAKI S80?
A water outlet C2 thermistor abnormality in your Hitachi Air Conditioner can be caused by a loose, disconnected, broken or short-circuited connector.
What causes water DHWT thermistor abnormally (THM D-HWT) in my Hitachi YUTAKI S80?
A water DHWT thermistor abnormality in your Hitachi Air Conditioner can be caused by a loose, disconnected, broken or short-circuited connector.
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.
