*Note
In multi-mode such as hot water “and” cooling shown in the layout, the heat pump will
always take the hot water mode as priority. As most system designs will use the internal
hot water heat exchanger in the EcoULTRA tank, it will require that the hot water tank is
first satisfied before activating a cooling call. This will ensure hot water is always present if
using the system for on-demand hot water. In the summer month when cooling is
preferred over domestic hot water the system can be switched to cooling only to bypass
the hot water demand.
