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 Err06 or FAN ERROR mean on a Thermor electric radiator?

Error Err06 or FAN ERROR indicates the blower/fan is not functioning correctly. This only appears on models with integrated fans. Check that the filter is clean and airflow is not obstructed. If the fan is not spinning, contact a qualified engineer for inspection.

What does error code W.50.3 mean on a Thermor Aeromax Split heat pump water heater?

Error W.50.3 indicates a communication error between the outdoor unit and the interface card. Check that the outdoor unit receives proper electrical power. A qualified engineer should inspect interconnection wire 3 and test the coil circuit, relay, and high-pressure switch on the external unit.

What does error code W.9 mean on a Thermor heat pump water heater?

Error W.9 indicates the water temperature is excessively high, exceeding 80°C. This is a safety protection. Switch off the water heater and allow it to cool completely. Check if the supplemental electric heater is operating continuously. If the mechanical safety device has triggered, it may need to be reset by a qualified engineer.

What does error code Err10 mean on a Thermor electric radiator?

Error Err10 indicates a communication fault between the motherboard and thermostat control. Cut power for 2 minutes, then restart. If the error persists, contact your installer or a qualified engineer as this indicates an internal electronic fault.

What is Frost Protection mode and when should I use it?

Frost Protection (also called HG or Hors Gel) maintains the room temperature at approximately 7°C to prevent freezing. Use this mode when you are away from your home for more than 48 hours during cold weather.

What should I do with my heat pump water heater during an extended absence?

For absences of less than two months, close the water inlet valve at the safety group. For absences longer than two months, close the water inlet, drain the tank completely, and ideally allow it to dry out. This prevents stagnant water issues and protects the system during extended periods without use.

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.

What are the different operating modes on Thermor heat pump water heaters?

Thermor heat pump water heaters typically offer four main modes: Auto mode uses energy sources optimally with the heat pump prioritising operation before electric backup; ECO mode uses renewable energy only and adapts to your consumption patterns; Manual mode allows you to set hot water quantity independently; and Absence mode reduces activity during scheduled periods away.

What should I do for short and long absences with Thermor radiators?

For absences of less than 2 hours, do not adjust the controls. For absences of 2 to 24 hours, lower the control by two positions or switch to Eco mode. For absences longer than 48 hours, use Frost Protection mode to maintain 7°C.
