Controls Configuration & Adjustments

Level-2 (Dealer-Service) Microprocessor Programming

(Includes Configuration for External Controllers)

Level-2 programming involves configuring the controller for specific site characteristics. To explain, this programming is where the controller is set to operate with, or without, an external 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 Technical Support Group, the installer should not adjust sensor calibration or dead-band values.

CAUTION !	Failure to heed the following may result in equipment dam-

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.

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 pass 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.
