HEATER CONTROLS...continued

Operational & Programming Codes

THE FOLLOWING CODES WILL BE DISPLAYED AS PART

OF THE NORMAL OPERATION OF THE HEATER:

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 oF.

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 !	Failure to heed the following may result in equipment damage
	and voiding of manufacturer’s warranty.

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.
