The system may take some time to heat up the water if it starts operating at a cold water temperature.
Why is my Panasonic WH-ADC0309K3E5AN system hard to heat up?
When the panel and the floor are heated simultaneously, the warm water temperature may decrease, which may reduce the heating ability of the system. Also, when the outdoor air temperature is low or the preset water outlet temperature is low, the system may need a longer time to heat up. Check that the discharge outlet or intake inlet in the outdoor unit is not blocked by any obstacle, such as a pile of snow.
Why does my Panasonic WH-ADC0309K3E5AN Heat Pump operation start automatically when the timer is not set?
If the timer is not set but the operation starts automatically, it is because the sterilization timer has been set.
Why is my Panasonic Heat Pump making a loud refrigerant noise?
Loud refrigerant noise that continues for several minutes is caused by protection control during de-ice operation when the outdoor ambient temperature is lower than -10 °C.
Why does my Panasonic WH-ADC0309K3E5AN outdoor unit not operate?
The outdoor unit may not operate because of the protection control of the system when the outdoor temperature is out of the operating range.
Why is the backup heater automatically turned ON in my Panasonic WH-ADC0309K3E5AN Heat Pump when it is disabled?
The backup heater automatically turns on due to the protection control of the indoor unit heat exchanger.
