Menu → Information → System status → triVAI
– You can use this function to read whether the heat pump
or the back-up boiler (gas, oil or electricity) is currently
covering the heat demand. 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 heat demand than the back-up boiler.
