Adjusting the User Interface Module/Operational Modes
Water Temperature Adjustment
The water temperature can be adjusted from 95°F to 150°F.
Use the Up and Down Buttons
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 qualified 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 finished.
Operating Mode Descriptions
The operating modes can be changed by touching the
desired mode icon on the User Interface Module (see
Figure 11.)
NOTE: All buttons on the User Interface are touch sensitive
and require only a light touch to actuate.
Hybrid Mode - This is the default, recommended
setting. Combining high energy efficiency with
reduced recovery time. This mode uses the
HYBRID
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.
Efficiency Mode - Is the most energy efficient
mode. This mode uses the heat pump to heat
water in the tank. The elements are not used
EFFICIENCY
unless the ambient operating temperature
is below 45°F or above 109°F. If hot water
demands are not met in Efficiency Mode it may
be necessary to switch to Hybrid Mode.
Electric Mode - The water heater functions as
a conventional electric unit, relying totally on
ELECTRIC
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 Mode - The controller adjusts the
water temperature to approximately 60°F. This
VACATION
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.
NOTE: To activate the Vacation Mode touch the
vacation button. To deactivate Vacation Mode
touch the vacation button. IMPORTANT: The
anode protecting the tank requires power to the
unit to operate. Do not shut off power to the unit
for extended periods of time. If power must be
turned off for an extended period of time, drain
the tank completely.
