The TEC3M will change its state dependant on the standing voltage of the battery onto which it is connected. Under factory set condition, whilst the vehicle engine is running the relay expects to see a voltage exceeding 13.5V; when this voltage is reached and maintained it will change its state to a closed condition, supplying voltage to the auxiliary unit. When the voltage of the vehicle battery falls below 12.9V will it disengage the supply, so on a vehicle with a healthy battery it is normal to see the supply maintained to auxiliary source for a period of time after the engine is switched off. Adjusting the pot on the top of the device will vary the voltage the unit opens and closes the relay contacts.
