Ventilation running day and night
If the ventilation aggregate is running all day and night, there is probably a failure in the control system - typically a hanging switch, or programming error. This type of error is often not identified, and the energy consumption for both ventilation and heat/air-condition will therefore be unnecessary high for a long period of time. The life-time of the ventilation system will also be shortened.
Sensors used: PowerMoni Spot.
Method: The sensor is mounted on the cable to the ventilation aggregate. If the unit consumption does not go down "at night", you will be warned, so you can take action.
Alarm set-up: is added automatically for ventilation aggregate units, or can be added manually to other unit types. No other set-up is needed.
