2) when water temperature is higher:
The definition that so-called water temperature is higher is Tset > Tw > Tset-Δ H, although now water temperature but not arrive design temperature temperature also higher, therefore in two kinds of situation:
1) be not detected by using hot water, then unit stops heating, not switch mode.
2) use hot water detected, then in order to ensure that hot water is enough, then switch to electric heating pattern to rely on electrical heating to complete this heating.This no longer performs heating before having heated rear fault recovery.
When the situation that water temperature is higher is controlled, how to detect whether using hot water to become the essential condition whether switching electric heating pattern, the present invention detect whether use hot water to realize in the following way:
