Operating description
0
The system gives priority to the heat pump during domestic hot water production.
Recourse to the electrical back-up is only taken if the DP090 time delay has elapsed in domestic hot
water mode, unless hybrid mode is activated. In that case, hybrid logic takes over.
1
Domestic hot water production mode gives priority to comfort by accelerating domestic hot water pro
duction by simultaneously using the heat pump and the electrical back-up.
In this mode, there is no maximum time for domestic hot water production as the use of the back-ups
helps to ensure domestic hot water comfort more quickly.
