▪
In case the space heating/cooling request is OFF and the tank temperature
setpoint is reached, the unit can choose to buffer energy from the photovoltaic
panels in the room (only in case of room thermostat control) or in the DHW tank
instead of putting the photovoltaic panel energy on the grid.
In case of room buffering, the room will heat up or cool down to the comfort
setpoint. In case of tank buffering, the tank will heat up to the maximum tank
temperature.
▪
The goal is to buffer the energy from the photovoltaic panels. Therefore, the
capacity of the unit is limited to what the photovoltaic panels are providing:

▪
The safety functions (water pipe freeze prevention, drain prevention, room frost
protection, tank disinfection) and defrost are NOT overruled (capacity will not be
limited for these functions)
Forced on:
Similar to Recommended on, but there is no capacity limitation. The goal is NOT to
use the grid as much as possible.
