What to do if the red LED is lit and the tank temperature is greater than 95°C on my Danfoss Thermostat?
If the red LED is lit and the tank temperature exceeds 95°C, it indicates that the pump is either not running or cannot keep up. You should check the pump mode and connections and set the speed higher.
What to do if there is no alarm and the temperature flashes on my Danfoss SH-E01?
If there is no alarm and the temperature flashes, it means the pump runs but indicates high temperature or the pump does not run. You should set the speed higher, or the pump or pump output may be defective.
What does it mean if the red LED is lit and the display flashes F1 on my Danfoss SH-E01?
If the red LED is lit and the display flashes F1, this indicates a fault at sensor 1 (Collector). Check the connections and the sensor.
Why is the red LED lit and the display flashing F2 on my Danfoss SH-E01 Thermostat?
