Frequently Asked Questions - WH-SXC12D9E81 PANASONIC

How to adjust the water outlet temperature?

Access SETTING mode by holding the SET button for 5 seconds. Navigate with ▲/▼ to select the desired parameter (e.g., H20 Lo or H20 Hi), then press SELECT to adjust the temperature with ▲/▼. Confirm with SET.

How to activate silent mode?

Press the QUIET button on the control panel. The corresponding indicator lights up. This reduces outdoor unit noise but may decrease heating/cooling capacity.

What to do if an error code is displayed?

Note the error code (e.g., H76). Refer to the TROUBLESHOOTING section of the manual. If the problem persists, turn off the power and contact an authorized dealer. Do not attempt to repair yourself.

How to program the timer?

Press TIMER. Select the day with ▲/▼, confirm with SELECT. Choose the program (1 to 6), then set the time and mode (ON/OFF). You can also adjust the mode, quiet, or backup heating. Confirm with SET.

What is the outdoor temperature range for operation?

Heating: -20 °C to 35 °C. Cooling: 16 °C to 43 °C. Outside these ranges, the heating capacity drops and the unit may temporarily stop for protection.

How to maintain the outdoor unit?

Regularly clear snow, leaves, or any obstacles blocking air inlets and outlets. Clean the external filter at least once a year. For internal operations, contact an authorized dealer.

Can I use a water tank from another brand?

Panasonic does not guarantee proper operation or system reliability if a tank from another brand is used. It is strongly recommended to use a Panasonic tank.

How to activate tank sterilization?

In special setting mode (SET + CHECK 5s), set function 5t rL Fun to YES, then program the day, time, temperature (40-75 °C), and hold duration. Sterilization runs even in standby.

Why does the outdoor unit emit steam?

In heating mode, the outdoor unit emits steam during defrosting of the heat exchanger. This is normal. Condensation or evaporation may also occur depending on conditions.

What to do in case of prolonged power outage?

Disconnect the power. When restarting, set the day and time again using the CLOCK button. Temperature and timer settings are retained. If the unit does not operate, check the circuit breaker.

NON SERVICEABLE CRITERIAS

TURN OFF POWER SUPPLY then please consult authorized dealer under the following conditions:

• Abnormal noise during operation.
• Water/foreign particles have entered the control panel.
• Water leaks from Indoor unit.
- Circuit breaker switches off frequently.
• Power cord becomes unnaturally warm.

The following symptoms do not indicate malfunction.

SYMPTOM	CAUSE
Flowing sound during operation.	Refrigerant flow inside the unit.
Operation is delayed a few minutes after restarting.	The delay is a protection to the unit's compressor.
Outdoor unit emits water/steam.	Condensation or evaporation occurs on pipes.
Outdoor unit emits steam during heating mode.	This is due to defrost operation happens at the heat exchanger.
Outdoor unit does not operate.	When the outdoor temperature is out of the operation condition range, the heatpump system enter protection control.
Air-to-Water Heatpump system operation will turn off.	The heatpump system enter protection control. Compressor stops by water inlet temperature lower than 18°C; and backup heater power turn on by water inlet temperature lower than 23°C.
System difficult to heat-up.	When heating is operated by indoor unit together with floor heating or panel heater simultaneously, there may be case where warm water temperature is getting lower and cause floor heating or panel heater heat-up is weaken.When outdoor air temperature is low, it may be difficult to get warm.Is the snow pile blocking the discharge outlet or intake inlet of outdoor unit.When water outlet set temperature is low, it may be difficult to get warm.
System cannot get warm instantly.	Due to the nature of the heatpump system, it may take some time to heat-up the water if the unit is operated from cold-start.
Backup heater turn ON automatically when it is not enabled.	The turn ON of backup heater is a protection to the indoor unit's heat exchanger.
Operation starts automatically even without ON Timer.	The sterilization timer has been set.

Check the following before calling for servicing.

SYMPTOM	CHECK
Heating/cooling operation is not working efficiently.	Set the temperature correctly.Is the panel heater/cooler valve closed.Clear any obstruction at the air inlet and air outlet vents of outdoor unit.
Noisy during operation.	Check if the unit has been installed at an incline or the cover is not closed properly.
The unit does not work.	Check if the circuit breaker is tripped.
Operation LED is no lit or control panel display is blank.	Is the power supply off or power failure.

The operation LED blinks and error code appear on control panel display.
