Whole-Room Heater 720S

1. E2 (Temperature sensor short circuit): Unplug it from the power source and contact Customer Support.
2. E1 (Temperature sensor open circuit): Unplug it from the power source and contact Customer Support.
3. FF (Overheat protection): Unplug and wait for it to cool down before plugging in again.
4. P4 (Tip-over protection): Place the heater back on a flat, level and stable surface.

1. Make sure the power cord is properly plugged into a powered electrical outlet.
2. If overheat protection has been activated, unplug the heater and let it cool down before plugging it in again, and remove any objects on or near the heater.
3. Check that your circuit breaker or fuse is working properly, and make sure the heater is placed on a flat, even surface.
4. If the set temperature is lower than the ambient temperature, raise it above the ambient temperature.

1. If the temperature has exceeded the thermal cutoff threshold, turn off and unplug the unit, then let it cool down before plugging it back in.
2. If the heater has tipped over, place it back on a flat, level and stable surface.
3. In ECO mode, the heater automatically turns off once the set temperature is reached — this is normal. If it turns off too frequently, raise the set temperature or switch to Power Heat mode.
