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.
The Language Selection screen should be
displayed.
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 by 2 degrees.
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
TEMPERATURE SCALE
desired offset. The last number shown on the
FAHRENHEIT / CELSIUS
display will become active.

OFFSET = -2 TO +2

Defrost Cycle

The UltraTemp Heat Pump 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.
Passive Cycle
The passive defrost cycle initiates when the refrigerant
sensor detects refrigerant temperature below
the defrost set point. At this time, the heat pump
compressor stops. The heat pump 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.
Note: The efficiency of a heat pump decreases as
air temperature decreases. For maximum efficiency,
operate the heat pump during the warmest time of day.

Run Time Counters

Details of the Run Time Counter abbreviations are listed
below:
COMP = COMPRESSOR
FAN = EVAPORATOR FAN
REV VLV = REVERSING VALVE (COOLING CYCLE)
FLT PMP = FILTER PUMP (AUTOSET/EXTEND FEATURE)
DEFROST = DEFROST FEATURE
RUN TIME = total time of the current cycle
LOG TIME = accumulated time of all cycles since the
last time the unit was powered on
CYCLES = number of cycles since the last time the
unit was powered on
WARRANTY HOURS = accumulated time of all cycles
over the lifespan of the unit
WARRANTY CYCLES = number of cycles over the
lifespan of the unit
Press the UP and DOWN arrows to scroll through the
Timers and Counters. The last screen provides an option
to reset the Run Time, Log Time and Cycles counters.
The Warranty Hours and Warranty Cycle Counter cannot
be reset.
