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.
What to do if Hitachi YUTAKI S80 has Receiver Communication failure?
If your Hitachi Air Conditioner is not receiving a signal, check the Opentherm/Hlink connection.
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 to do if Hitachi YUTAKI S80 Air Conditioner shows Increase in the inverter fin temperature or abnormality?
Check cooling conditions for the inverter.
What causes suction pressure decrease prevention to activate in my Hitachi YUTAKI S80 Air Conditioner?
Activation of suction pressure decrease prevention in your Hitachi Air Conditioner can be caused by a shortage or leakage of refrigerant, piping clogging, a close-locked expansion valve, or a locked fan motor.
What causes inverter fin temperature thermistor abnormality in Hitachi Air Conditioner?
Inverter fin temperature thermistor abnormality in your Hitachi Air Conditioner can be caused by a loose, disconnected, broken or short-circuited connector.
What to do if Hitachi YUTAKI S80 shows Thermostat Heater Alarm?
If your Hitachi Air Conditioner is showing a high temperature in the electric heater, check the electric heater for proper operation.
How to troubleshoot Hitachi Air Conditioner hydraulic alarm flow and water pump malfunction?
If your Hitachi Air Conditioner displays a hydraulic alarm related to flow and water pump malfunction, check the water pump for proper operation and repair or replace it if defective. This alarm indicates that water flow is not detected in the hydraulic cycle or the pump is defective.
What causes Hitachi YUTAKI S80 to activate safety device from excessively low suction pressure?
If your Hitachi Air Conditioner activates the safety device from excessively low suction pressure, inspect refrigerant levels and piping for blockages. This issue is often due to a shortage or leakage of refrigerant, piping clogging, a closed expansion valve, or a locked fan motor.
Why does my Hitachi YUTAKI S80 activate safety device from excessively high discharge pressure?
If your Hitachi Air Conditioner activates the safety device due to excessively high discharge pressure, inspect the heat exchanger and refrigerant conditions. This activation can be caused by overload (obstruction of HEX, short circuit), a mixture of inert gas, or excessive refrigerant.
