Sensor cable has short-circuited or the 

sensor is possibly defective.

Check connection and/or sensor ca-

ble. Possibly check sensor and sensor 

cable using an ohmmeter.

Loading of the storage tank/pool was 

deactivated due to storage priority.

If this is not wanted, loading can be 

reactivated via storage priority or 

season selection.

The collector is in a stagnant state, 

pump starts are blocked in order to  

prevent damage.

Wait until the collector has cooled 

sufficiently before setting these 

values.
