To Next PageTo Next PageWhat does Activation of protection control for excessively high pressure mean on Hitachi YUTAKI S80?
If your Hitachi Air Conditioner displays 'Activation of protection control for excessively high pressure', inspect system pressure and performance. The system stops after P12 retry due to discharge pressure Pd exceeding 2.78 MPa for 10 seconds.
What does Activation of low control mean on Hitachi Air Conditioner?
If your Hitachi Air Conditioner displays 'Activation of low control', inspect system low-pressure conditions. The system stops after P06 retry due to Ps being less than 0.15 MPa for 90 seconds.
What does Excessively low pressure difference mean on Hitachi Air Conditioner?
If your Hitachi Air Conditioner displays 'Excessively low pressure difference', check for proper pressure differences in the system. The system stops after P11 retry due to pressure ratio being less than 1.8 for 3 minutes.
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.
