Frequently Asked Questions - S125MW1E5 PANASONIC

What are the operating modes of the Panasonic S125MW1E5 heat pump?

The unit offers two main modes: Tank Mode (for domestic hot water, adjustable temperature from 35°C to 65°C) and Air Conditioning Mode (water cooling or heating). In air conditioning mode, you can use the heat curve function which automatically adjusts the water temperature based on the outdoor temperature.

How to adjust the water temperature in tank mode?

In Tank Mode, press the ▲ or ▼ buttons on the remote control to adjust the water outlet temperature between 35°C and 65°C. The setting is displayed on the screen.

What to do if the heat pump does not start?

First check that the power supply is active (circuit breaker on). If the circuit breaker tripped, contact a technician. Then make sure the remote control is turned on (ON/OFF button). If the problem persists, check the error codes on the screen.

How to maintain the heat pump?

Only clean the exterior with a soft cloth. The interior must be cleaned by a professional. Regularly check that the air inlets and outlets are not obstructed. Never use solvents or very hot water on plastic parts.

What do error codes like E03 or F01 mean?

Error codes appear on the remote control screen in case of malfunction. For example: E03 = remote control communication error, F01 = refrigerant sensor anomaly. Most reset automatically; if the code persists, contact your dealer.

Can I use the unit below 0°C?

Yes, in heating mode, the outdoor unit operates down to -20°C (wet bulb). However, heating performance decreases with outdoor temperature. If necessary, auxiliary heating can be used ('External device ready' signal).

How to activate the anti-legionella sterilization function?

In the Hydraulic module menu in Tank mode, activate the Sterilization timer. Set the day and time. Sterilization heats the water to a high temperature (above 65°C) for about 4 hours. Beware of hot water (risk of burns).

What to do in case of water leakage?

If water leaks from the indoor unit, immediately stop the unit and cut the power supply. Contact a professional. Condensation is normal during cooling, but significant leakage indicates a problem.

Does the heat pump work after a power outage?

Yes, the unit automatically resumes operation after a temporary power failure, retaining previous settings. However, if the outage is prolonged, it is recommended to cut the power to save energy.

How to save energy with this unit?

Use the Energy saving function in the menu. In cooling mode, close curtains to limit sunlight entry. In heating mode, do not block water inlets/outlets. Keep the water clean and set temperatures reasonably.

Operation Mechanism

■ Heating Performance

- Since this Air-to-Water utilizes outside air for heating, its heating performance deteriorates as outdoor temperature decreases. (Due to heat pump system) Information called “External device ready demand” is outputted from terminal of electrical component box.

Use another heating appliance using this information, etc.

- It will take some time until the supplied water temperature becomes warmer after heating operation started.

■ Defrosting

- This appliance may start defrosting operation to melt frost form in the outdoor unit during long hour heating operation mode.

The indoor unit including Air-to-Water will stop for about 5 to 10 minutes at this time.

■ Heating Standby

The remote controller shows “⚙️” (Heating standby) on the display in the following mode and heating capacity will be limited.

- When operation started

- When Thermostat activated

- When defrosting

■ When Heating Operation Started (Only 3WAY VRF)

When changed to heating mode from stopped or cooling operation mode, the unit does not work for about 3 minutes for the sake of self-protection.

It may take about 5 to 10 minutes until the hot water is delivered after starting the heating operation.

Oil Recovery

The water pump may run at a slow speed in order to recover the oil in the system every 1 to 3 hours during cooling or heating operation.

The unit will automatically resume the original operation after about 5 to 10 minutes.

■ Remote Control Sensor

The temperature sensor in the Air-to-Water normally senses the water temperature and can also sense the ambient temperature of the remote controller. (room temperature) For the details, consult the shop you purchased.

■ Should the power failure occurs while the unit is running

When the unit automatically resumes operation after temporary power failure, it uses the same settings before the power was cut off.
