Ventilation needs service
If the ventilation starts spending more energy than normal, in the running cycle, it might need service. I.e. if the bearings are worn out, or there is dirt in the fan. Both indicate that service is needed, before the ventilation breaks down.
Sensors used: PowerMoni Spot.
Method: The sensor is mounted on the cable to the ventilation aggregate.
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.
