Eco-Time

Note: The Eco-Time setting is only active when
Efficiency Mode is set to "Hybrid".
In some cases, the heat pump alone will be unable
to heat incoming water to the active set point within a
specific period of time. In these cases the gas heater
will turn on to provide supplemental heat.
The Eco-Time setting is the period of time the heat
pump will attempt to heat to the active set point before
the gas heater activates to provide supplemental heat.
Both the Pool Set Point and Spa Set Point have an
individual Eco-Time setting.
To change the Eco-Time setting:
1. Press the UP and DOWN arrows simultaneously.
2. Press the MENU SELECT button repeatedly until
the Eco-Time screen is displayed.
TIME = 1-6 HOURS
3. Press the UP or DOWN arrows to select the
desired duration. The last value displayed will
become active.

Boost Temperature

Note: The Boost Temperature setting is only active
when Efficiency Mode is set to "Hybrid".
In some cases the heat pump alone will be unable to
heat incoming water to the active set point as a result
of unusually low water temperature. If the difference
between the actual incoming water temperature and
the active set point exceeds a set amount, the gas
heater will turn on to provide supplemental heat.
The Boost Temperature setting is the difference
between incoming water temperature and the active
set point which will activate the gas heater. Both the
Pool Set Point and Spa Set Point have an individual
Boost Temperature setting.
To change the Boost Temperature setting:
1. Press the UP and DOWN arrows simultaneously.
2. Press the MENU SELECT button repeatedly until
the Boost Temperature screen is displayed.
POOL BOOST TEMP
3. Press the UP or DOWN arrows to select the
desired temperature. The last value displayed will
become active.

Temperature Scale - C˚ or F˚
The control board can display temperatures in either
degrees Fahrenheit or Celsius. The temperature scale
in use can be changed from the Service Menu tree as
described below:
1. Press the UP and DOWN arrows simultaneously.
2. Then press the MENU SELECT button repeatedly
until the Temperature Scale screen is displayed.
3. Press the UP or DOWN arrows to toggle between
the Fahrenheit and Celsius options. The last option
shown on the display will become active.
Water Temperature Offset
The control board provides the ability to increase or
decrease the displayed water temperature.
To change the temperature offset:
1. Press the UP and DOWN arrows simultaneously.
2. Press the MENU SELECT button repeatedly until
the Temperature Offset screen is displayed.
3. Press the UP or DOWN arrows to select the
desired offset. The last number shown on the
display will become active.

OFFSET = -2 TO +2

Defrost Cycle

The UltraTemp ETi™ Hybrid Heater may enter a
defrost cycle if air temperatures are around 50°F
(10°C). To enter a defrost cycle the Defrost feature
must be enabled in the Service Menus.
The passive defrost cycle initiates when the evaporator
sensor detects refrigerant temperature below the
defrost set point. At this time, the heater compressor
stops. The heater evaporator fan will continue to run,
and will draw air over the evaporator fins for about 15
minutes.
If the refrigerant sensor detects a temperature above
the defrost stop temperature, the compressor will
restart. If defrost stop temperature is not reached
within 15 minutes the unit will shut down and display a
"Low Ambient Temp" alarm.
