10.6.- Anti-legionella function (optional) (with hot water tank only)
This optional function prevents the bacteria causing legionnaire’s disease from proliferating in the
hot water accumulated in the tank. Every 7 days, the temperature of the water in the tank is raised
to 70 ºC to kill any such bacteria. This function will only run if the boiler is left switched on.
The boiler is supplied with this function disabled. To enable it, carefully read the "
Installation
Instructions
" section. We recommend that the operation for enabling this function is carried out by
qualified personnel.
