Turning on the water heater.

 

There is no power button for this unit.  Once the water heater is 

wired and power is supplied, it will be on. The display will show 

the current water temperature setting.  Current operating mode 

for the water heater is illuminated. 
To comply with safety regulations, the controls are factory 

preset to 120°F (49°C) and Hybrid Mode. It is recommended 

that the unit be set to Heat Pump (only) mode to maximize 

energy savings.  Operating in Hybrid mode provides a balance 

of energy savings and hot water use convenience.  Reported 

energy consumption is based on operating the unit in Hybrid 

mode at a temperature setting of 135°F (57°C), and operation 

at lower temperature settings or in Heat Pump (only) mode will 

provide even greater energy savings.
