Aquacal Heat Pump

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.

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 dif fer by 2 to 3oF, calibration is necessary.

Perform calibration procedure as follows:

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

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