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.
What causes water swimming pool thermistor abnormally (THM SWP) in my Hitachi Air Conditioner?
A water swimming pool thermistor abnormality in your Hitachi Air Conditioner can be caused by a loose, disconnected, broken or short-circuited connector.
What causes indoor unit number setting error in my Hitachi YUTAKI S80?
Indoor unit number setting error in your Hitachi Air Conditioner can be caused if indoor units with the same number exist in a refrigerant piping system.
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 Abnormality of picking up circuit for protection (Outdoor unit) in Hitachi Air Conditioner?
If your Hitachi Air Conditioner displays 'Abnormality of picking up circuit for protection (Outdoor unit)', inspect indoor unit PCB and wiring. The cause can be a failure of indoor unit PCB, incorrect wiring, or connection to PCB in the indoor unit.
What to do if Hitachi Air Conditioner shows Failure of discharge gas pressure sensor?
If your Hitachi Air Conditioner displays a 'Failure of discharge gas pressure sensor', check the connectors for any looseness or breakage. The issue may be a loose, disconnected, broken, or short-circuited connector.
What causes Failure of suction gas pressure sensor in Hitachi YUTAKI S80?
If your Hitachi Air Conditioner displays a 'Failure of suction gas pressure sensor', check the connectors for any looseness or breakage. The problem may stem from a loose, disconnected, broken, or short-circuited connector.
What causes Water inlet thermistor abnormally (THMwi) in Hitachi YUTAKI S80?
If your Hitachi Air Conditioner displays any of the following errors: Water inlet thermistor abnormally (THMwi), Water outlet thermistor abnormally (THMwo), Indoor Liquid Pipe Temp Thermistor Abnormality (THMl), Indoor Gas Pipe Temperature Thermistor Abnormality (THMg), Water Circuit 2 thermistor abnormally (THMwo2), Water DHW thermistor abnormally (THMdhwt), Auxiliary sensor 2 thermistor abnormally (THMaux2), Auxiliary sensor 1 thermistor abnormally (THMaux1), Water Plate HEX pipe thermistor abnormally (THMwohp), Suction R134a pipe thermistor abnormally (THMs), Discharge R134a pipe thermistor abnormally (THMd), check the connectors for any looseness or breakage. The cause may be a loose, disconnected, broken or short-circuited connector.
