Operational & Programming Codes
FLO..... No Water Flow Detected. This code appears whenever the circulating
pump is off, or when the heater is not receiving correct water flow.
OFF..... System is Off. This code appears whenever heater has been turned off
via the mode selector button, or when the temperature set point has been
lowered below 45
CFI...... Celsius/Fahrenheit Selection. This is a programming entry point to select
in which format the water temperature will be displayed.
ULC.....User Lock Code. This is a programming entry point; when activated,
steps to the next menu level: ELC.
ELC..... Enter Lock Code. This a programming entry point; permits end user to
select a secret code, thereby limiting access to the owner settings.
CFO.....Call Flex Options. This is a programming entry point; when used in
conjunction with a AquaCal Call/Flex add on kit, permits the use of CALL
or FLEX options.
FS....... Heater in Defrost Mode. This code appears as a normal display during
periods of lower air temperatures. Two possibilities follow:
Heat-Only Units: Fan continues to run and compressor is off. Compressor
will restart when air coil temperature rises to approximately 38°F.
Heat-Cooling (reversing) Units (Applicable in Heat Mode Only): if a
defrost cycle is necessary, the unit's reversing valve will be activated.
While the reversing valve is activated, the fan operation will be
suspended to permit maximum heating of the air-coil. The reverse-cycle
will continue until the air-coil reaches a set temperature, or until 4-Minutes
has elapsed. Upon completion of the defrost cycle, the reversing valve
will be deactivated; normal fan and heating operation will resume. During
hot-gas defrost cycles, the compressor will not deactivate; rather, it will
continue in operation throughout the sequence.
LOC.....This is a Service Entry Point (not intended for use by the owner). The
[LOC] code permits service personal to enter a factory code for access to
adjustable calibration and site-dependant setup parameters. Service
adjustments are available to authorized installation and service
personnel, only.
CAUTION !
Heat pumps contain no owner-serviceable components. Owner-initiated adjustments, beyond
the controller "LOC" code, must not be attempted. If adjustments are deemed necessary, the
owner should contact installing dealer or AquaCal Customer Support at (800) 786-7751.
