What does error code W.51.4 mean on a Thermor Aeromax Split heat pump water heater?

Error W.51.4 indicates a current/intensity sensor fault on the outdoor unit. This affects the system's ability to monitor electrical current properly. Contact a qualified engineer to verify and potentially replace the outdoor unit control board.

What does error code W.50.2 mean on a Thermor Aeromax Split heat pump water heater?

Error W.50.2 indicates a communication failure between the regulation board and interface card. Check the power supply to the outdoor unit and interface card. A qualified engineer should verify interconnection wires 1 and 2, and inspect the communication cable between the circuit boards.

What does error code Err 01 mean on a Thermor electric water heater?

Error Err 01 on Thermor Duralis models indicates the battery powering the ACI Hybrid anti-corrosion circuit is no longer effective. Wait for 2 complete off-peak heating cycles (approximately 16 hours) for the battery to fully charge. If the error persists, the thermostat assembly may need replacement.

What does error code W.30.1 mean on a Thermor heat pump water heater?

Error W.30.1 indicates the heat pump has been running for 20 hours without reaching the target temperature, or there is a lack of thermal exchange. Check for hot water leaks and ensure adequate ventilation. Contact a qualified engineer to verify refrigerant charge and check for clogged circuits.

What does error code Err03 mean on a Thermor electric radiator?

Error Err03 indicates the temperature sensor is faulty or not properly connected. Switch off the radiator and check for visible loose connections near the sensor. If the error persists after power cycling, contact a qualified engineer to replace the temperature sensor.

Are Thermor water heaters protected against Legionella bacteria?

Yes, all Thermor electric water heaters include anti-legionella protection. The water temperature cannot be set below 50°C, which prevents bacterial growth. Legionella bacteria thrive between 23°C and 43°C, so maintaining temperatures above 50°C eliminates this risk.

What size water heater do I need for my household?

Calculate approximately 40 to 50 litres of hot water per person per day. For a family of four, this means a 150-200 litre tank is typically suitable. Underestimating leads to cold showers, while overestimating increases energy costs from heating unnecessary water.

How does the electronic thermostat work on Thermor radiators?

Thermor's electronic thermostat uses a sensor that permanently measures room temperature and transmits values to an electronic controller. The thermostat controls the heating element's working time to reach but not exceed your set temperature, with high precision of ±0.5°C.

Why does my Thermor heat pump water heater make noise?

Heat pump water heaters produce operational noise from the integrated heat pump compressor and ventilation fan during heating cycles. This is normal operation. Thermor recommends installing these units in non-habitable spaces such as a utility room, garage, or cellar rather than near living areas or bedrooms.
