Modes of Operation

eHeat 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 3-4 hours to initially heat a tank to 120F at
room temperature (4-6 hours in a colder room). Approximately one hour to
reheat from a 10 gallon flow.
Hybrid Mode – combines the energy efficiency of eHeat with the recovery
speed and power of the electric elements. The control automatically uses
efficient eHeat unless the majority of hot water is consumed.
Standard Electric Mode – uses the upper and lower heating elements to heat
the water. Heats water the fastest, but is the least energy efficient mode.
High Demand Mode – use this mode if your household has higher than
average water usage. The control will automatically use efficient eHeat if
water usage is normal, but when demand is higher, then standard electric
will be used.
