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 an

AquaCal Call/Flex add on kit, permits the use of CALL or FLEX options.

FS....... Heater in Defrost Mode (Applicable to Heat-Only Units, only). This code appears as a

normal display during periods of lower air temperatures. Sequence follows:

Heat-Only Defrost Sequence: Fan continues to run and compressor is off. Compressor will restart when air coil temperature rises to approximately 38°F.

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
CAUTION !	and voiding of manufacturer’s warranty.
