7. Choose the day and time to start the anti-legionella programme.
In installations equipped with a low loss header or a buffer tank connected
as a low loss header, it is necessary to activate the Buffer tank function.
1. Configure the buffer tank parameters.
The system does not allow the simultaneous production of heating and
domestic hot water. It is possible to alter the parameters to adapt the
operation of the product to your needs.
1. The timer programming for domestic hot water production can be
altered based on your night-time habits, for example.
2. If modification of the timer programming is not sufficient, go into the
domestic hot water setting parameters:
