Menu → Information → System status → triVAI
– You can use this function to read whether the heat pump
or the auxiliary heater (gas, oil or electricity) is currently
covering the energy requirement. The energy manager
uses the triVAI and the comfort criteria to decide which
heat generator to use.
If the value that is read is greater than 1, the heat pump is
better at covering the energy requirement than the auxiliary
heater.
Menu → Information → System status → Battery status
– You can use this function to read the battery's state of
charge.
– OK: The battery has sufficient charge.
– Critical: The battery is almost flat.
