Modes of Operation
Heat Pump Mode
– most energy-efficient mode, uses only the sealed system. The time required to heat
water is longer, but should be adequate for normal demand households. it will take 3 to 4 hours to initially
heat a tank to 120°F at room temperature (4 to 6 hours in a colder room). it will take approximately 1 hour to
reheat from a 10-gallon flow.
Hybrid Mode
– combines the energy efficiency of heat pump mode with the recovery speed and power of
the electric elements. The control automatically uses the efficient heat pump mode, unless the majority of
hot water is consumed.
High Demand Mode
– use this mode if your household has higher than average water usage. The control will
automatically use the efficient heat pump mode if water usage is normal, but when demand is higher, the
electric mode will be used.
Electric Mode
– uses the upper and lower heating elements to heat the water. Heats water the fastest, but is
the least energy-efficient mode.
Vacation
– Use this mode when hot water is not needed for an extended period of time. The control will drop
the temperature down to 50°F (10°C) and automatically return to the previous operating mode, heating the
water to the original temperature setting on the day before the total input of days selected.
Three Heat Sources
The water heater has 3 heat sources:
1. Upper Element
2. Lower Element
3. Condenser
Note:
Only 1 heating source can be on at a
time. The upper heating element has priority.
if a large temperature increase is required,
the upper element is used (except in heat
pump mode).
