Overheated Room Thermostat - E0004.04

The E0004.04 alarm appears on Rika pellet stoves when the room temperature measured by the thermostat exceeds 30 °C.

Solution

1. Let the room cool down (open a window, move the thermostat away from a heat source)
2. The message cannot be acknowledged until the temperature drops below 30 °C

Make sure the thermostat is not too close to the stove or another hot appliance.
