What does error code W.24 mean on a Thermor heat pump water heater?

Error W.24 (Info24) is an informational message indicating the air temperature is outside the ranges tolerated by the refrigerant fluid. Ensure the unit has adequate ventilation and the air inlet is not obstructed. In extreme temperatures, the electric backup heater will activate automatically.

What does error code W.30.5 mean on a Thermor heat pump water heater?

Error W.30.5 indicates a mismatch between water heater settings and the ducting installed, or aeraulic pressure losses are too high. Check the ducting parameters in the installer menu and verify thermal exchange. If the fault clears when inlet ducting is removed, the ducting may need reconfiguration.

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 does error code 3 or W.23 mean on a Thermor electric water heater?

Error 3, W.3 or W.23 indicates a water temperature control fault related to a temperature sensor anomaly. This stops heating to prevent abnormal temperature rises. Restart by cutting power for 30 seconds. If the error persists, a qualified engineer needs to inspect the temperature sensor.

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.

How do I operate the pressure relief valve on my Thermor water heater?

Operate the pressure relief valve's lever monthly to avoid jamming from scale deposits. Lift the lever briefly to release a small amount of water and ensure the valve moves freely.

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.

How often should I clean the air filter on my heat pump water heater?

Clean the air filter annually under normal conditions, or every six months if the unit is installed in a dusty environment. A clogged filter reduces heat pump efficiency and can lead to insufficient hot water production. The filter is accessible without tools and can be cleaned with a vacuum or soft brush.

Why is my Thermor towel rail not heating up?

First check the thermostat is set to the desired temperature and functioning correctly. For electric models, check the fuse in the wall switch. If the controller appears to work but no heat is produced, the heating element may have failed.

What heating modes are available on Thermor towel rails?

Thermor towel rails typically offer Comfort mode for when you are present, a reduced temperature mode for when the room is unoccupied (recommended for absences over 2 hours), and Frost Protection mode set at approximately 7°C for extended absences.
