The heater has no operating voltage.

Check 12 V DC voltage supply and fuses, charge the 12 V battery if necessary, and switch the heater off and on again to clear blocked automatic restart.

The temperature set on the control panel is lower than the ambient room temperature.

Set a higher room temperature on the control panel using the rotary knob.

230 V AC voltage supply is not available.

Check the 230 V AC voltage supply, vehicle fuses, and fault circuit breakers.

12 V DC voltage supply is outside the tolerance range (must be between 10.4 V and 16.1 V).

Charge the 12 V battery, replace an outdated battery if necessary, and check voltage sources such as the charger.

Frequently Asked Questions

Q: What should I do if smoke and odours occur during first-time use?

A short period of smoke and odour formation can occur during initial commissioning or after long periods of inactivity due to dust and dirt. Ensure good room ventilation and switch on only the fan (circulated air mode) for a short time.

Q: Can I dry clothes or towels on the Eezy heater?

No. Never hang textiles, blankets, or towels in front of or on the heater to dry, as this causes severe overheating and poses a major fire hazard.

Q: What campsite fuse rating is required for each power level?

Eco mode (900 W / 230 V / 4 A) requires a minimum 6 A campsite fuse; Max mode (1800 W / 230 V / 8 A) requires a minimum 10 A campsite fuse; Night mode (450 W / 230 V / 2 A) requires a minimum 4 A campsite fuse.
