Why does my Panasonic Air Conditioner outdoor unit emit water or steam?
The emission of water or steam from your Panasonic Air Conditioner's outdoor unit is due to condensation or evaporation occurring in the pipes.
Why is my Panasonic WH-UD12HE8 system hard to heat up?
Your Panasonic Heat Pump system may take longer to heat up if the panel and floor are heated simultaneously, which can decrease the warm water temperature and reduce heating ability. Also, low outdoor air temperature or a low preset water outlet temperature can extend the heating time. Check if the discharge outlet or intake inlet in the outdoor unit is blocked by obstacles like snow.
Why does my Panasonic WH-UD12HE8 system not heat up instantly?
If the system starts operating at a cold water temperature, it will take some time to heat up the water.
What to do if operation in HEAT/COOL mode is not working efficiently in Panasonic WH-UD12HE8?
If your Panasonic Heat Pump's HEAT/COOL mode isn't working efficiently, make sure the temperature is set correctly. Close the panel heater/cooler valve. Also, check the outdoor unit and clear any obstructions from the air inlet and outlet vents.
Why does steam come out of the Panasonic Air Conditioner outdoor unit in the heating mode?
Steam coming out of the Panasonic Air Conditioner outdoor unit in heating mode is caused by defrost operation in the heat exchanger.
Why is my Panasonic Air Conditioner backup heater automatically turned ON when it is disabled?
If the backup heater in your Panasonic Air Conditioner turns on automatically when disabled, it's due to the protection control of the indoor unit heat exchanger.
Why does loud refrigerant noise continue for several minutes in my Panasonic Air Conditioner?
The loud refrigerant noise in your Panasonic Air Conditioner is caused by protection control during de-icing operation when the outdoor temperature is lower than -10 °C.
Why does my Panasonic WH-UD12HE8 backup heater automatically turn on when it is disabled?
The backup heater may turn on automatically due to the protection control of the indoor unit heat exchanger.
Why is my Panasonic Air Conditioner outdoor unit not operating?
The Panasonic Air Conditioner outdoor unit might not operate due to the system's protection control when the outdoor temperature is outside of the operating range.
