Aquacal Heat Pump

1. Entering Service Menu:

A. To enter the service menu, Simultaneously press and hold both the [UP ARROW] and

[DOWN ARROW] keys until [CF1] (Celsius / Fahrenheit) code appears. (Note: if “000”

displays, the User Lock Code is enabled, and the ULC pass code must be entered before

proceeding. See Owner-Level Operating Instructions, page-15: “User Lock Code Option

[ULC].” If the owner’s ULC p ass code is unknown, the factory default code “17” may be used

to access controller programming.) Press the [POOL/SPA] key four times to display [LOC],

which is the entrance point for the Service Menu.

B. The [LOC] code function allows service personnel to use an access code to enter the

service menu. This section of the programming is intended for authorized factory service

personnel, only .

C. Using the [UP] and [DOWN] arrow keys, scroll the displayed number to “50.” (“50” is the

default service entry pass code.)

D. Once the correct service code is displayed, pressing the [POOL/SPA] key–once again–will

allow access to the service menu.

E. The first service parameter displayed will be [dEL] (4 -minute time delay on make).

NOTE: Pressing the [POOL/SPA] key will save the displayed value in any menu parameter,

and will advance to the next service menu juncture.

Controls Configuration & Adjustments

Level-2 (Dealer-Service) Microprocessor Programming

(Includes Configuration for External Controllers)

Failure to heed the following may result in equipment dam-

age and voiding of manufacturer’s warranty.

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 inst alling dealer or AquaCal Customer Support at (727-823-5642).

Level-2 programming involves configuring the heat pump microprocessor for specific site character-

istics. To explain: this programming is where the heat pump microprocessor is set to operate with, or

without, an external “pool equipment” controller; where sensor calibrations are performed; and where

changes to other factory default parameters are made.

Before transferring use of the heater to the owner , the installer must insure the controller programming

is compatible with any site-installed external controllers, and that the heater starts and operates per

the manufacturer’s specifications.

Generally speaking, the installer ’s main focus within Level-2 programming will be in configuring for

external controller compatibility. And, unless instructed to do otherwise by the AquaCal T echnical

Support Group, the installer should not adjust sensor calibration or dead-band values.
