If your WAREMA Control Systems display the message 'Attention: Overload at +12V. Switch off the system and eliminate the cause,' it indicates a short circuit at +12V at the sensor terminals. To resolve this, switch off the unit. Then, connect the sensor supply lines one after the other until the fault message reappears. Correct the fault at the sensor or the line causing the short circuit.

* Damaged connection terminals (too tight): Send the device in for repairs.
