12.1.5 Setting Water Outlet Temperature for Heat Mode

The set temperature defines the parameters for the outdoor ambient temperature dependent operation of the
unit. Where by the internal water setting temperature is determined automatically depending on the outdoor
temperature. The colder outdoor temperatures will result in warmer water and vice versa. The user has the
possibility to shift up or down the target water temperature by control panel setting.

Outdoor temperature is updated every 30 minutes when operation ON.

Setting water outlet temperature always follow H20 (Lo) or H2O (Hi) whenever is higher if outdoor ambient
sensor or indoor communication error happen.
