Water Temperature Adjustment
The water temperature can be adjusted from 95°F to 150°F.
Use the Up and Down Buttons
on the front
panel to set the desired temperature.
IMPORTANT:
Before attempting to adjust the thermostat,
read the “Water Temperature Regulation” section. If the
instructions are not clear, contact a quali
fi
ed person.
IMPORTANT:
Filling a spa or hot tub from this water heater
may result in extended recovery/re-heat time. Switching
(temporarily) to Hybrid Mode or Electric Mode will decrease
the recovery/re-heat time. Be sure to switch back to the
desired operational mode when
fi
nished.
Operating Mode Descriptions
The operating modes can be changed by touching the
desired mode icon on the User Interface Module (see
Figure 10.)
NOTE:
All buttons on the User Interface are touch sensitive
and require only a light touch to actuate.
EFFICIENCY
Ef
fi
ciency Mode - Is the most energy ef
fi
cient
mode. This mode uses the heat pump to heat water
in the tank. The elements are not used unless the
ambient operating temperature is below 45°F or
above 109°F. If hot water demands are not met in
Ef
fi
ciency Mode it may be necessary to switch to
Hybrid Mode.
HYBRID
Hybrid Mode (recommended setting) - Combines
high energy ef
fi
ciency with reduced recovery time.
This mode uses the heat pump as the primary
heating source. The heating element will heat
water if demand exceeds a predetermined level so
that the set point temperature can be recovered
more quickly.
ELECTRIC
Electric Mode - The water heater functions as a
conventional electric unit, relying totally on the
elements to heat the water in the tank. This mode
may be useful in winter to eliminate the output of
cold air from the unit.
VACATION
Vacation Mode - The controller adjusts the water
temperature to approximately 60°F. This mode is
recommended when the water heater is not in use
for a long period of time. This mode minimizes
energy consumption and prevents the water heater
from freezing during cold weather.
Other Controls
Lock - Holding this button for more than 3
seconds switches the lock mode on or off. When
the User Interface Module is locked a symbol
and “Lock” text will be visible on the display (see
Figure 10).
°F/°C
°F/°C - The button switches the display to show
the set temperature in Fahrenheit or Celsius.
