2.Time Delay [dEL]:

A.With the [dEL] (4 minute time delay) code message displayed use the [UP] or [DOWN] arrow key to select either “1” to allow the time delay to remain active or “0” to deactivate the time delay. Not pressing any buttons for 15 seconds will allow the controller to save the selection and return to the normal operating mode. Pressing the {POOL/SPA] key will also save the selection and step to the next menu parameter: [JAO] (External Controller Interface).

B.CAUTION!!!: The time delay should only be deactivated for service convenience and must be reactivated prior to placing the heat pump back is service. Failure to reset the time delay feature could result in permanent damage to the heat pump compressor.

3.Configuring for External Controllers [JAO] or [FS2]:

A. Configuring for External Controllers Using [JAO] Selection:

NOTE: FOR WIRING TO AN EXTERNAL

CONTROLLER, REFERENCE DOCUMENT

LTP0050 SHIPPED WITH HEATER.

1)Follow the steps 1, A through 1, D to enter the service menu. Once [dEL] is displayed, press the [POOL/SPA] key until the display shows [JAO].

2)With the [JAO] (External Controller Interface) code message displayed, use the [UP] or [DOWN] arrow keys to select either “0” to disable the External Controller Interface, “2” to connect a thermostat type controller (2-wire connection). Apply [FS2] configuration to connect a thermostat selector type controller (3-wire connection); see “3. B,” below. Do NOT use [JAO] “3.”

B.Configuring Remote Flow Switch / Automatic Thermostat Switching Using [FS2] Selection:

1)Follow the steps 1, A through 1, D to enter the service menu. Once [dEL] is displayed, press the [POOL/SPA] key until the display shows [FS2].

2)With the [FS2] (Remote Flow Switch / Automatic Thermostat Switching) code message displayed, use the [UP] or [DOWN] arrows to select either “0” to disable Remote Flow Switch / Automatic Thermostat Switching, “1” to enable Remote Flow Switch / Automatic Thermostat Switching.

NOTE: ALL FLOW SWITCH KITS PRODUCED BY AQUACAL ARE SHIPPED WITH FULL INSTALLATION AND PROGRAMMING INSTRUCTIONS. PLEASE CONTACT AQUACAL CUSTOMER SUPPORT (800-786-7751)IF ADDITIONAL COPIES OF THESE INSTRUCTIONS ARE NEEDED.

4.Water Sensor Calibration [tSC]:

If it is believed the displayed pool or spa water temperature does not match the actual temperature, follow the steps below to verify and adjust the controller as necessary. Be certain to use an accurate thermometer:

A.With the circulating pump in operation, and water moving through the heater, use a reliable thermometer to measure the temperature of the pool or spa water. Be sure to measure the water temperature away from returns. The object is to accurately determine the temperature of the water entering the heater.

B.Once you have measured the water temperature, compare the result to the heater’s displayed water temperature. If the water temperatures are the same or within 1oF, no calibration is necessary. If the temperatures differ by 2 to 3oF, calibration is necessary.

Perform calibration procedure as follows:
