AUTO mode
This mode automatically selects the energy source for maximum savings, while guaranteeing that the
water is sufficiently hot.
The water heater always selects the heat pump first. If the air temperatures are not in the operating range,
or if a fault is detected in the heat pump, the electric backup is automatically selected to guarantee a
sufficient volume of hot water.
